Comparison of peritoneal tumor imaging using conventional MR imaging and diffusion-weighted MR imaging with different b values.

Purpose: The aim of this study was to evaluate the utility of DW MRI with two different b values in identifying peritoneal tumors in oncology patients.

Materials And Methods: Nineteen patients with known malignancy underwent abdominal and pelvic MRI before surgery. MRI included free-breathing DWI with b values of 400 and 800 s/mm2, T1-weighted fat-suppressed spoiled gradient-echo, T2-weighted fat-saturated turbo spin-echo, and 5-min delayed gadolinium-enhanced imaging.

Hepatic arterial mapping by multidetector computed tomographic angiography in living donor liver transplantation.

Purpose: Our aims were to present the hepatic arterial variations that were detected with computed tomographic angiography (CTA) and confirmed by operation in living liver donors and to emphasize the usefulness of CTA in the assessment of hepatic arterial anatomy.

Materials And Methods: The donors of 100 patients (46 women and 54 men) who had undergone a living donor liver transplantation in a (blinded) hospital between July 2004 and June 2007 were evaluated. The age of the donors ranged from 18 to 63 years (mean, 39 years).

Computed tomography findings in diseases of the adrenal gland.

The adrenal gland is a common site of disease, with an abnormality prevalence as high as 9% in autopsy series. With the increasing use of CT, adrenal lesions are frequently found in the daily practice of radiology and are diagnosed in up to 5% of CT examinations performed for varied reasons. Imaging features on CT can establish a specific diagnosis of many of these lesions, including myelolipoma, hematoma and cysts.

Images in clinical urology. Why we did not use left side for this donor.

We describe a case of an unusual variation of the double retroaortic left renal vein discovered during routine donor examination of the abdomen by multidetector computed tomography. A 53-year-old man underwent evaluation in our department as a potential renal donor for his brother who had end-stage renal failure. Multidetector computed tomography angiography showed double retroaortic left renal veins.

Coronary artery-pulmonary vein fistula diagnosed by multidetector computed tomography.

Coronary artery fistulas are rare congenital or acquired coronary artery anomalies that can originate from any of the three major coronary arteries and drain in all the cardiac chambers and great vessels. Multidetector computed tomography has provided cross-sectional anatomy of the heart with excellent spatial and temporal resolution, which shows the anatomical and functional changes in cardiac disorders. Here, the first case of noniatrogenic coronary artery to pulmonary vein fistula depicted by multidetector computed tomography has been presented.

Infra-renal abdominal aorta hypoplasia in a case of Down syndrome depicted by multidetector computed tomography angiography.

We report the case of a 3-day-old newborn with Down syndrome suffering from congenital infra-renal aortic hypoplasia. To our knowledge, this is the first report of a Down syndrome case with infra-renal abdominal aorta hypoplasia depicted by multidetector computed tomography angiography. In cases with no palpable pulsations in the lower extremities, multidetector computed tomography angiography is a fast and reliable diagnostic tool for the evaluation of distal aortic lesions.

Presence of obestatin in breast milk: relationship among obestatin, ghrelin, and leptin in lactating women.

Objective: The peptide hormones ghrelin and leptin have been found in blood and breast milk. This study was undertaken to investigate whether breast milk also contains obestatin, which is derived from the same gene as ghrelin but has opposite actions, and to characterize the relations among serum and milk ghrelin, obestatin, and leptin levels in lactating mothers.

Methods: Venous blood, colostrum, and mature milk were obtained from healthy lactating women (n = 31) just before suckling.

[Diagnostic value of HASTE technique and excretory MR urography in urinary system obstructions].

Purpose: To compare the diagnostic value of static-liquid magnetic resonance urography (MRU) in T2-weighted HASTE (half-fourier acquisition single-shot turbo spinecho) sequences and T1-weighted excretory MRU with i.v. diuretic and contrast material injection.

Renal replacement lipomatosis: MR findings in one case.

Replacement lipomatosis of the kidney is the result of severe atrophy or destruction of the renal parenchyma, often caused by calculous disease with secondary marked proliferation of renal sinus, renal hilus, and perirenal fatty tissue. Different diagnostic tools have been used to define this entity, with ultrasonography (US), i.v.
