Ulrasound imaging

Maddibande Ramachar Sreevathsa, Khyati Melanta
Between January 2012 to 2016, 20 patients with primary hyperparathyroidism underwent surgical exploration for presumed diagnosis of parathyroid adenoma. Nineteen patients underwent ultrasonography of neck and USG was found to be accurate in localizing the adenoma in 84.2%. Seventeen patients underwent sestamibi isotope scanning and imaging correlated with operative findings in 94.1%. Combined accuracy of ulrasound and sestamibi scan which was done in 17 patients was 95%. Seventeen patients underwent unilateral exploration and there was resolution of disease in 94...

Musculoskeletal ultrasound (US) is noninvasive, nonionisating and cost-effective imaging diagnostic technique. It is a useful imaging modality for the diagnosis of joint and soft tissue pathology and can be considered as an extension of physical examination. Elbow is easily accessed due to its superficial position. A high resolution, multi-frequency (10-15 MHz) linear transducer should be used. US investigation of the elbow includes scanning of the anterior, medial, lateral and posterior part of the joint. Common flexor and extensor origin at the humearal epicondyles, triceps tendon, distal biceps tendon and ulnar nerve should be analised...

The design, implementation, and testing of a computational observer method for objective evaluation of ultrasound images are presented. The method uses digitized ultrasound B-scan images of a test phantom (the contrast-detail phantom), and is able to calculate the detectability of a target (signal) from its background (background noise). A quantitative detectability index, based on the measured signal-to-noise ratio of the image data, that is measured for both the human and the computational observer on the same scale is generated...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
