Further investigations
In some cases examination and plain x-rays are not enough to make a full diagnosis of your knee problem. This because soft tissues around the joint are not clearly seen on x-ray. Further investigations may be required using scans to give more information leading to a diagnosis.
X-rays are a type of radiation called electromagnetic waves that create black and white pictures of particular body parts. The varying shades of black and white indicate how much radiation each part of the body tissue is absorbing; bones appear as white because they absorb the most, fat and other soft tissue appear grey because they absorb less. An x-ray can be particularly useful especially when investigating a new injury as the resulting images will show if any bone in your leg is broken (fractured), dislocated (out of place) or if some other issue is affecting the bone.
Ultrasound imaging of the knee uses sound waves to produce pictures of muscles, tendons, ligaments, nerves and the joint. It can be helpful in diagnosing sprains, strains, tears, trapped nerves, arthritis and other musculoskeletal conditions.
Computed (Axial) Tomography (CT or CAT) scans combine x-rays with computers to produce 360-degree, cross-sectional view of a body part. These investigations can show what’s happening in the bones, soft tissue and blood vessels surrounding your knee.
Unlike x-rays and CAT scans, MRI scanning uses a strong magnetic field and radio waves and can create pictures of any organs and tissues in the body. An MRI scan of your knee can show the soft tissues, such as ligaments and tendons, that aren’t detectable on an x-ray. This method of investigation is very valuable to provide detailed information to Mr Mandalia before a treatment plan is decided.
Investigations using x-ray or scans are common practice and will help Mr Mandalia to better understand your condition. A Consultant Radiologist will report on any image or scan and send the report, as well as the diagnostic images, to Mr Mandalia.
