Ultrasonography is a safe and relatively inexpensive imaging modality which is often used as the initial screening method to investigate suspected tumours and other disorders in various parts of the body. The department is equipped with two B/W ultrasound scanners - the RT 3200 and Sterling units, as well as two colour doppler Scanners - the Logiq 500 and Logiq 700 units. All of these are equipped with a variety of multifrequency sector, linear and convex probes. These scanners allow examination of the abdomen, pelvis and other organs such as the breast, scrotum, thyroid and eye with a high degree of sensitivity. they provide useful information regarding the size and extent of tumours, lymphnode enlargement and metastatic deposits in the liver and other organs. Special Endorectal and Endovaginal probes are used to obtain better visualization of the pelvic organs and prostate gland. The Colour Doppler scanners enable colour flow studies to be added to the ultrasound examinations to evaluate blood flow and velocity and assess tumour vascularity. Narrowing and thrombosis of blood vessels can be diagnosed with this technique. The top-of-the-line Logiq 700 unit incorporates features such as Tissue Harmonic Imaging, Coded excitation and 3-D imaging, which permit high resolution images of superficial and deep structures to be obtained.

Bedside sonography is carried out in the ICU using the two Portable Ultrasound Scanners - the Capasee and SDR 1200 units. These scanners are also employed for intraoperative sonography, especially for evaluation of the liver, gall bladder and pancreas, using a specialized high frequency intraoperative probe. The CMF-800 Endovascular Ultrasound unit which is a very special equipment, also useful for research is available for detailed assessment of blood vessels using a special intravascular probe and useful for endovascular brachytherapy.
