A qualitative and quantitative assessment of simultaneous strain, shear wave, and point shear wave elastography to distinguish malignant and benign breast lesions.

Background: Ultrasound (US) elastography has become a routine instrument in ultrasonographic diagnosis that measures the consistency and stiffness of tissues.

Purpose: To distinguish benign and malignant breast masses using a single US system by comparing the diagnostic parameters of three kinds of breast elastography simultaneously added to B-mode ultrasonography.

Material And Methods: A total of 163 breast lesions in 159 consecutive women who underwent US-guided core needle biopsy were included in this prospective study.

The effect of retroperitoneal fat tissue thickness on testicular venous drainage.

Introduction: We evaluated a possible effect of the amount of retroperitoneal fat tissue on testicular venous drainage to shed light on the mechanism of varicocele occurrence.

Patients And Methods: A total of 132 patients with no fertility complaints were included in this study. Retroperitoneal fat thickness (RPFT) was measured during abdominal computed tomography examinations.

Portal venous diameter in children: normal limits according to age, weight and height.

Purpose: To establish the normal limits of portal vein diameter according to age, height and weight.

Materials And Methods: One hundred and sixty-eight healthy children, ages ranging from 1 month to 15 years were examined by ultrasound. Portal vein diameters at hepatic port, weight and height were recorded.

Detection of cytochrome P450-2A6, -3A5 and -4B1 with real-time polymerase chain reaction in prostate tissue.

Cytochrome P450 (CYP) is a heme-containing enzyme superfamily metabolizing a wide variety of xenobiotics, including drugs and carcinogens. The majority of CYP genes are expressed in the liver, however, some CYP isoforms are also reported for a number of extra hepatic tissues. We analyzed Cytochrome P450-2A6, -3A5 and -4B1 mRNAs using real-time reverse-transcriptase polymerase chain reaction (RT-PCR) in a total of 21 homogenized prostate tissues with or without malignancy.

The prevalence and variations of inferior right hepatic veins on contrast-enhanced helical CT scanning.

Purpose: To present the prevalence and variations of inferior right hepatic veins (IRHVs) on contrast-enhanced helical computed tomography (CEHCT) scans.

Materials And Methods: The routine abdominal CEHCT scans of 349 patients were reviewed. Three hundred and eight patients (88.

[Unenhanced spiral CT in the diagnosis of acute appendicitis].

Purpose: To evaluate the role of unenhanced spiral computed tomography (CT) in the work-up of patients with suspicious symptoms of acute appendicitis.

Materials And Methods: Sixty-five patients with suspected acute appendicitis (34 (52%) women and 31 (48%) men), were studied with spiral CT without administration of IV or oral contrast. From the upper L1 vertebral plate to the superior border of the iliac wings, slices of 10 mm collimation with 8 mm/sec table speed were taken, and from that level to the acetabular roof level, 5 mm thick slices were obtained with a table speed of 5 mm/sec and tube rotation time of 1.
