Objective: This prospective study was undertaken to assess the sensitivity and specificity of color flow mapping and pulse Doppler waveform in identifying malignancy preoperatively in adnexal masses in perimenopausal women. Materials and methods: A total of 100 cases with adnexal masses in perimenopausal women were scanned, underwent color flow mapping and pulsed Doppler waveform studies. These...

Doppler color flow mapping in conjunction with two-dimensional echocardiography was used to evaluate ventricular septal rupture after myocardial infarction (seven anterior and eight inferior) in 15 patients and to correlate these findings with cardiac catheterization and surgical or autopsy data. Ventricular septal rupture was diagnosed by turbulent flow traversing the ventricular septum. The d...

Color Doppler and intravenous angiography (digital technique) can widely be used in experimental medicine. Their wide clinical application, availability, simplicity and small cost impose their importance. Color Doppler analysis of the vascular activity of certain region is more precise than the classic intravenous angiography, but requires contact of highly sophisticated equipment with the expe...

Introduction: Two percent of all 1st trimester pregnancies in the United States are ectopic. Transvaginal ultrasound is considered the mainstay in diagnosis. Color Doppler ultrasound can prove to be an added helpful modality in identifying ectopic pregnancies. Case report: An 18-year-old nulliparous female presented with vaginal bleeding and lower abdominal pain. Pelvic exam revealed tenderness...

BACKGROUND The clinical utility of ankle-brachial index (ABI) is not clear in subjects with less severe or calcified vessel. Therefore, we investigated the usefulness of color Doppler ultrasonography for diagnosing peripheral artery disease (PAD) in type 2 diabetes mellitus (T2DM) subjects. METHODS We analyzed 324 T2DM patients who concurrently underwent ABI and carotid intima-media thickness...

Doppler–Imaged Flow Convergence Region: Limitations To the Editor: I would like to congratulate Ishii et al1 for a very interesting study in the February 6, 2001, issue of Circulation on the use of 3D reconstruction of the color Doppler–imaged flow convergence region in ventricular septal defects. Their study, however, fails to mention 2 significant limitations of the flow convergence method. F...
