Radiological Anatomy

Medical Physics Education

Internal organs and parts in the body are analyzed using radiographic images. It is essential to have an accurate interpretation of the images so as to provide the best and accurate diagnosis or treatment for the patients. Imaging modalities in use at various clinical sites in the country are X-ray radiography, Ultrasound, CT-Scan, SPECT, MRI and NMR among others.

The appearance of body tissues or organs depends on their abilities to block or absorb radiations. In systems employing x-rays, this is known as radio-opacity. The increasing radio-opacity from air ( that appears white on
conventional radiographic film or computerized tomograms, and black on fluoroscopic screens ) , fat, soft tissues like heart, kidney, and muscles, calcifics like skeleton, enamel of the teeth, and dense foreign bodies.
