Detection of Subpubic Tumor Causing Bladder Outlet Obstruction by 3D Perineal Ultrasound

2015

This case report shows that 3D perineal ultrasound can be superior to clinical examination and routine 2D perineal ultrasound in the detection of an unusual subpubic tumor. A 73-year-old female patient was referred to our urogynecological outpatient unit complaining of over-active bladder symptoms and voiding dysfunction for 3 years. Gynecological examination found no signs of pelvic organ prolapse or abnormality in the vaginal cavity. Routine 2D perineal ultrasound showed substantial residual urine (ca. 300 ml on catheter) and limited bladder neck mobility, but no signs of pelvic organ prolapse. Use of standardized 3D perineal ultrasound revealed a 24 × 26 × 32 mm spherical, hypoechoic tum…

Congenitally corrected transposition of great vessels: MRI and echocardiographic appearance

1995

This paper presents the case of a 36-year-old male with congenitally corrected transposition of great vessels (CTGV). This is a rare cardiac anomaly characterized by atrioventricular and ventriculoarterial discordance, occuriing in less than 1% of all congenital heart diseases. This was diagnosed by echocardiography and MRI. The MRI findings demonstrated cardiac abnormality.

Endometrial receptivity: evaluation with ultrasound.

2013

An adequate endometrial receptivity is a crucial factor for embryo implantation. We describe endometrial morphology (endometrial appearance or pattern, endometrial thickness, volume, and delimitation), based on the concepts and possibilities of the new ultrasound modalities (3-dimensional/4-dimensional ultrasound, automatic volume calculation, virtual organ computer-aided analysis, tomographic ultrasound image, inverse mode, and 3-dimensional Doppler angiography) as markers of endometrial receptivity.

Significance of ultrasound for the diagnosis of hypertrophic pyloric stenosis

1986

The sonographic features of hypertrophic pyloric stenosis (HPS) were evaluated in a 5-year prospective study (1981–1985) at the University Clinic of Pediatric Surgery in Mainz. In 37 cases real-time ultrasound was performed preoperatively to measure muscle thickness, diameter, and length of the pylorus; the recorded values were compared with those of a control group. Muscular wall thickness proved to be the most reliable parameter, while pyloric canal length was the most difficult measurement to obtain. Diameter alone was not adequate to establish the sonographic diagnosis, which depends on the individually and functionally different luminal width and submucosal thickness. Significant sonog…

Is x-ray compulsory in pubic symphysis diastasis diagnosis?

2013

SirWe read with great interest your case of postpartum symphy-sis pubis separation (1). We would like to present a case ofpubic symphysis diastasis that we diagnosed with a differentapproach.A 36-year-old gravida 1 para 0 at 39.6 weeks’ gestation wasadmitted with the onset of spontaneous contraction. After threehours and 18 min she delivered a 3170 g baby without compli-cations.Three hours after delivery, she complained of severe pain inthe symphysis pubic region. On examination, there was localtenderness in that region. We performed an ultrasound exami-nation, which revealed a 15.2-mm gap in the region of the sym-physis pubis (Figure 1), diagnosed as pubic symphysis diastasis.She was given…

Intravascular Ultrasound-based Imaging Modalities for Tissue Characterisation

2014

Atherosclerosis is the leading cause of cardiovascular mortality and morbidity in the developed world. Intravascular ultrasound (IVUS) is a widely used imaging modality providing complementary diagnostic information to angiography regarding the vessel wall of the coronary arteries. IVUS has been used for assessment of ambiguous angiographic lesions, evaluation of new interventional devices and in atherosclerosis progression-regression trials. However, the standard gray-scale IVUS has limited value for the accurate identification of specific plaque components. This limitation has been partially over- come by introduction of new IVUS-based imaging methods such as: virtual histology IVUS, iMAP…

[CT-angiography in carotid stenosis].

1997

Purpose: Prospective evaluation of the accuracy of CT angiography (CTA) with different postprocessing for extracranial carotid artery in comparison with DSA. Method: one hundred patients were studied with standarized CTA. For postprocessing, MPR, MIP, and 3D reconstruction based on segmentation with upper and lower threshold were used. Intravascular density profiles were considered. All CTA studies were correlated with intra-arterial angiography. The degree and classification of stenoses was determined using the guidelines established by the NASCET collaborators. Results: Measurement of stenosis was possible by MPR in 82.5 %, by MIP in 85 %, and 3D in 100 %. Correct classification was found…

Coronary plaque imaging with multislice computed tomography: technique and clinical applications.

2006

The composition of an atherosclerotic lesion, rather than solely the degree of stenosis, is considered to be an important determinant of acute coronary events. Whereas until recently only invasive techniques have been able to provide clues about plaque composition with consistent reproducibility, several recent studies have revealed the potential of multislice computed tomography (MSCT) for noninvasive plaque imaging. Coronary MSCT has the potential to detect coronary plaques and to characterize their composition based on the X-ray attenuating features of each structure. MSCT may also reveal the total plaque burden (calcified and noncalcified components) for individual patients with coronar…
