MRI or Magnetic Resonance Imaging is a process of reproducing images from the structures & organs of the insides of the body on the computer screen with the help of energy pulses generated from the radio waves using a magnetic field placed inside a special machine.
MRI is used to diagnose various medical conditions like internal injuries or bleeding, rupture of blood vessels & other internal infections. However, an MRI scan is also useful for diagnosis of brain tumors, brain strokes, spinal tumors, bone tumors, ruptured ligaments, breast cancers, aneurysm etc. MRI scan is also used to detect problems in liver, gallbladder, kidneys, eyes and ears that are otherwise unrecognisable.
On comparing it with other similar imaging processes like ultrasound imaging, CT scans & X-rays, you will come across the following facts:
- MRI can effortlessly produce images from different directions & orientations of one particular structure.
- MRI is also helpful for getting detailed & precise images of soft tissues in comparison to similar imaging processes.
- MRI provides a macroscopic overview of the body in contrast to other imaging processes like ultrasound which concentrates on a minute examination of your body parts.
- MRI is also useful to determine the limit to which cancer has spread in the body.
- MRI can be useful to detect health issues when other imaging processes fail, because of its multi-faceted image recording technique.
My mom having abdominal pain. Usg shows antero inferior wall uterine fibroid measuring 1.8×1.7 cm. Need any surgical intervention?
Papillary carcinoma thyroid After removal of thyroid gland, it's there any chance that the disease may relapse?
Gone are the days when bone ailments and damages were detected based on the experience and superficial conversations made by the physicians. These days with the advent of radio waves, medical science has made significant progress that has enabled a detailed overview of what exactly is going on inside your body and what should be the most relevant treatment in that regard. Magnetic Resonance Imaging or more commonly known as MRIs are a boon when it comes to diagnosing orthopedic and musculoskeletal complaints.
Common Uses of the Procedure:
MR imaging is usually the best choice for examining the:
- body’s major joints.
- spine for back pain
- soft tissues (muscles, tendons and ligaments) and bones of the extremities.
MR imaging is typically performed to diagnose or evaluate:
- degenerative joint disorders such as arthritis.
- tears of the menisci, ligaments and tendons (knee) or rotator cuff and labrum (shoulder and hip).
- fractures (in selected patients).
- spinal disk abnormalities (such as a herniated disk).
- the integrity of the spinal cord after trauma.
- sports-related injuries and work-related disorders caused by repeated strain, vibration or forceful impact.
- infections (such as osteomyelitis).
- tumors (primary tumors and metastases) involving soft tissues around the joints and extremities (such as muscles, bones and joints).
- pain, swelling or bleeding in the tissues in and around the joints and extremities.
- congenital malformations of the extremities in children and infants.
- developmental abnormalities of the extremities in children and infants.
- congenital and idiopathic (developing during adolescence) scoliosis prior to surgery.
- tethered spinal cord (abnormal stretching in the spinal cord) in infants and children.
In this process, X-rays and radio waves are subjected upon the affected region to examine the conditions of the bones, tissues, muscles and also detect the presence of tumours. This is majorly a non-invasive test and is painless. It does not use ionizing rays and therefore does not harm the body in any which way. The MRIs capture a detailed picture of the organs and the internal body structures and then transmit them onto a computer screen for the physician to monitor the inside story.
- MRI is an imaging technique that does not require exposure to radiation.
- MR images of the soft-tissue structures of the body (particularly muscles, bones and joints) are often clearer and more detailed than with other imaging methods. This detail makes MRI an invaluable tool in early diagnosis and evaluation of many conditions, including tumors.
- MRI can distinguish abnormal tissues from normal tissues much more accurately than most other imaging tests (x-ray, CT, etc.).
- MRI enables the discovery of abnormalities that might be obscured by bone with other imaging methods.
- The contrast material used in MRI exams is less likely to produce an allergic reaction than the iodine-based contrast materials used for conventional x-rays and CT scanning.
- MR images allow the physician to clearly see even very small tears and injuries to tendons, ligaments and muscles and some fractures that cannot be seen on x-rays and CT. If you wish to discuss about any specific problem, you can consult a radiologist.
Radiology is a branch of medicine that deals with diagnosis and treatment of diseases using radiant energy. Radiology uses the imaging technology like ultrasound, x-ray radiography, Magnetic Resonance Imaging (MRI), Computed Tomography (CT), Positron Emission Tomography (PET), nuclear medicine. The imaging technology helps the doctor (or physician) to see within the human body and helps you get diagnosed and treated in a better way.
Radiology is also referred to as radioscopy or clinical radiology where the latter refers to the diagnosis and treatment of fatal injuries/diseases. Radiologist is a doctor who has specialized in radiology after completion of a formal medical course to become a certified doctor. Radiographer is in turn a technician who specializes in the physical operation of scans and machines like x-rays etc. You must be well aware that the Radiologist is a professional doctor but the Radiographer is just a technician.
The following are the various uses of radiology when it comes to monitor the activity of your heart:
- MRI: It is known as Magnetic Resonance Imaging and it makes use of the energy stored in your body’s hydrogen atoms. It uses highly advanced computer 2-D and 3-D images and no ionizing radiation is used in MRI. The activity with the heart can be precisely recorded by MRI scan.
- Nuclear medicine: It involves giving your body a small tracker or a radioactive material which records the radiation coming from your body using special cameras like gamma cameras or PET. It can measure the complexity of your heart disease.
- Fluoroscopy: It helps to give real time visualization of the body by using x-rays that allow the doctor to efficiently monitor the body part, joint and bones as well as the activity that pertains to the heart.
- Ultrasound: It is a test which uses high frequency sound waves to form an image within the insides of any human organ like blood vessels or the heart. Many prefer this form of imaging test which uses sound waves instead of radiation and is considered less harmful.
- Computed Tomography: In this type of scan, a 3-D image is formed through several 2-D images taken at a single line of axis rotation. This test is useful as it gives detailed images of specific parts of the body like blood vessel, arteries, and soft tissues surrounding your heart.
What is computed tomography?
Computed Tomography is more commonly known as CT scan. It is a specialized form of X-ray. Computed Tomography is a non-invasive diagnostic procedure. CT scan provides concise images of different body parts and can also divulge any internal bleeding or injury during emergency situations. It is absolutely painless and is known to provide accurate information.
How does it work?
The patient is required to lie down on a table which is then passed through an opening, circular in structure. The radiations are rotated inside the CT scan machine for processing the images of the required body parts.
Benefits of Computed Tomography
- Computed Tomography helps in the identification of any benign (tumor) or malignant (cancer) growth in any part of your body.
- The procedure can be conducted for different body parts such as the head, abdomen, spine and chest among many others.
- The images provide much detailed information. It contains information regarding the condition of blood vessel, soft tissue and bones.
- Various bones and muscular disorders are also identified via Computed Tomography.
- Radiation therapy or biopsy can be carried out with the aid of Computed Tomography.
Risk factors associated with Computed Tomography
- If a person is allergic to Iodine (a dye used in the process), then it must be informed to the doctor beforehand to avoid further complications such as itching, nausea or vomiting.
- At times, kidney functions may get disrupted.
- The radiation emitted during CT scan is known to be harmful, especially for children.
- The dye used for conducting CT scan can cause allergic reaction that can be life-threatening.
At times the doctor may advise anti-allergic drugs to patients who are allergic to the dyes used in the process. CT scan is otherwise a very safe procedure for diagnosing various diseases.

Ultra sound is commonly known as sonography. It is a process of reproducing ultrasound images of soft tissues of a particular body part and other organs on the computer screen with the help of the echoes of the sound waves produced by the transducer, a high-frequency generating instrument.
Ultra sound is commonly used during the different stages of pregnancy to denote the foetal health, date of delivery, birth defects etc. However, in recent times, the ultra sound has also been associated with the diagnosis of other body parts such as the eyes, heart, gall bladder, liver, ovary, uterus, kidney, uterus, testicles, and ovaries. Ultra sound has also been useful in conducting biopsies for suspecting cancer patients, although not all of the cancers are detected by this imaging process. 3D & 4D ultrasound imaging are useful for looking at a particular body portion with much more precision and in slow motion respectively.
The advantages of ultra sound are:
1. The process of ultrasound imaging is a painless and a fast one. It does not require any insertion of needles or similar objects to denote the problems of the concerned body part.
2. The process is more convenient as compared to other similar imaging processes like MRI, mammogram and x-rays as they can capture images of the soft tissues, blood flow & cysts more clearly than the other processes.
3. The process is free of any harmful effects as there are no chances of exposure to radiation as compared to similar processes such as CT scans or X-rays. If you wish to discuss about any specific problem, you can consult a doctor and ask a free question.
A lower limb ulcer or a leg ulcer is characterized by the formation of a chronic sore. These sores take more than a month to heal, and tend to develop on the insides of the leg. It is characterized by symptoms of pain, swelling in the affected area and itching. The skin around the ulcer tends to harden and get discolored. A foul smelling discharge is also common.
These sores tend to form if there is a minor injury in the leg. This tends to develop when the blood circulation inside the veins of the leg is hampered, that results in an increase in blood pressure. The high blood pressure can damage the vessels under the skin, making them fragile. The skin tends to break and form ulcers easily after a cut or a wound has been sustained.
There are certain factors that increase the risks of lower limb ulcer; them being:
Obesity: Being overweight can lead to an increase in blood pressure in the leg, augmenting the risk of lower leg ulcer (learn more to reduce obesity)
Varicose Veins: This disorder is characterized by swollen veins resulting from malfunctioning valves. This disorder of the veins increases the risks of lower limb ulcers.
Age: Ageing increases the chances of lower leg ulcer. This is because old age and its related disorders tend to limit your movement.
The symptoms of lower limb include discoloration of the skin, swollen ankles, a heavy feeling in the lower limbs, flaky and itchy skin and enlarged veins in the legs. A foul smelling discharge from the wound and high fever are common symptoms as well.
The treatment begins with cleaning the affected area. Medicines are applied on the area, following which the dressing is applied on the wound. In order to treat the swelling and improve the circulation in the legs, a compression bandage is also wrapped around the area. These bandages help in easing the blood circulation and relieving pain.
In order to facilitate quicker healing of the ulcer, it is recommended to remain active and ditch a sedentary lifestyle completely. It is advised to keep your leg elevated while you are sitting or lying down; this helps better the blood circulation. Avoid smoking and consuming alcohol as they inevitably slow down the healing process.
Radiology is a specialized branch of science concerned with the treatment and diagnosis of diseases through high energy radiation or X-rays. Interventional radiology also known as vascular radiology is a subspecialty of radiology. Interventional radiology involves the use of a variety of techniques for diagnosing or treating a particular disease. Some of these techniques are Ultrasound, MRI (Magnetic Resonance Imaging) and X-ray among the others.
Radiology has several advantages. Six prime advantages of Radiology are mentioned below:
- Radiology and Interventional radiology are sometimes completely non-invasive or less invasive methods of diagnosis and treatment. These diagnostic and treatment procedures involve the use of digital imaging or photographic images and needle insertion.
- Radiology is a less expensive method of treatment as compared to other surgical or medicinal treatment procedures.
- Blood vessel diseases like narrowing of arteries, which obstructs smooth flow of the blood, hemorrhage, blood clots and vein blockage can be easily treated with the help of radiology.
- Radiology can effectively treat benign or malignant tumors. It destroys the tumor in situ (original position of growth) and also counters tumors that has spread to other parts of the body due to metastasis( the process through which cancer cells spread from its original position to the other organs of the body).
- The procedure of radiology can also be used for inserting feeding tube into a patient's body or for the purpose of draining out fluids from the abdominal region or chest.
- Radiology is considered to be a popular treatment for treating different stone diseases such as kidney stones or gallstones.
All radiological procedures are conducted by or under the supervision of experienced specialists known as Radiologists.
