Penile Doppler ultrasonography is a high-performing, noninvasive or minimally-invasive imaging modality that allows the depiction of the normal anatomy and macroscopic pathologic changes in real time. Moreover, functional changes in penile blood flow, as seen in erectile dysfunction (ED), can be analyzed using color Doppler ultrasonography (CDUS). This review article describes the normal sonogr...
The transabdominal ultrasonography (US) is recognized as a useful tool for the diagnosis of pancreatic diseases, it is also true that its essential weakness of “not being able to see through air” becomes a considerable handicap when observing the pancreas, which is for the most part located behind the gastrointestinal organs. Endoscopic ultrasonography (EUS) was developed to minimize the effect...
Ultrasonography is an elegant tool for the detection of tenosynovitis, synovitis, and erosions very early in rheumatoid arthritis, and the presence of a power Doppler signal is one of the best predictors of joint damage. Although clinical scores remain the mainstay of disease activity assessment, ultrasonography has proved to be a remarkably robust tool for reliable assessment of changes in rhe...
BACKGROUND Early and accurate diagnosis of post-surgical deep vein thrombosis (DVT) can be difficult and time-consuming, even with duplex ultrasonography. Portable continuous-wave Doppler ultrasonography may be useful in screening patients for postoperative DVT. Further confirmation of Doppler-positive cases by duplex ultrasound might then be more cost-effective. METHODS All major post-surgic...
Assessment of neck lymph nodes is essential in patients with head and neck cancers for predicting the patient's prognosis and selecting the appropriate treatment. Ultrasonography is a useful imaging tool in the assessment of neck lymph nodes. Greyscale ultrasonography assesses the size, distribution, and internal architecture of lymph nodes. Doppler ultrasonography evaluates the intranodal vasc...
Background & Aims: Intussusception is one of the most common causes of bowel obstruction in young children ultrasonography (US) is considered a reliable method for diagnosis. The primary treatment is hydrostatic radiologic reduction, but this should never be used in children with necrotic or perforated bowel. Clinical and radiologic prediction of intestinal necrosis is difficult. Color Dopple...
