HYPOTHESIS High-resolution ultrasound and technetium Tc 99m sestamibi scanning can be used for preoperative localization of abnormal parathyroid glands in patients with hyperparathyroidism. DESIGN Ultrasound and sestamibi scanning were performed in patients undergoing neck exploration for hyperparathyroidism. If the 2 scans agreed in identifying a single adenoma, and surgery confirmed the loc...

Isotope examination of the liver depends on the functional activity of the liver phagocytes, while ultrasound and CT scanning display the anatomical structure. Cold areas on an isotope scan may be due to impaired function or space-occupying lesions. The method is nonspecific and does not differentiate between cysts, abscesses and metastases. Both ultrasound and CT scanning can differentiate spa...

Ultrasound imaging, which is also called ultrasound scanning or sonography, is conducted by exposing part of the body to high-frequency sound waves to produce a visualization of the inside of the body. Ultrasound scanning is non-invasive, so it is usually painless. It is also widely available, easy-to-use and less expensive than other imaging methods. Because ultrasound imaging uses no ionizing...

Ultrasound scanning of a peripheral nerve along its expected course is a simple and useful method for determining the cause of peripheral neuropathy. We present 3 cases of peripheral neuropathy in which the pathology was detected by simple ultrasound scanning of the affected nerve. There were 2 cases of entrapment neuropathy due to mucoid cyst and 1 case of nerve sheath tumor. All lesions were ...

OBJECTIVE To evaluate the effectiveness of routine ultrasound scanning in pregnancy by a meta-analysis of various outcome measures. DESIGN Meta-analysis of randomised controlled trials evaluating the effect of routine ultrasound scanning on perinatal mortality and morbidity. Live birth rate (that is, live births per pregnancy) is included as a measure of pregnancy outcome in addition to the c...
