Aim: To determine the relationship between caudate-right lobe ratio (C/R) and model for end-stage liver disease (MELD) score.

Methods: The study included 50 patients with cirrhosis and a control group of 20 patients. C/R was measured as described by Harbin et al.

The course of habituation of the proboscis extension reflex can be predicted by sucrose responsiveness in Drosophila.

The proboscis extension reflex (PER) is triggered when insects' gustatory receptors contact appetitive stimuli, so it provides a behavioral readout for perceptual encoding of tastants. Research on the experience dependent modulation of PER in Drosophila has been hindered by the difficulty of obtaining reliable measures of memory-driven change in PER probability in the background of larger changes induced by physiological state. In this study, we showed that the course of PER habituation can be predicted by the degree of sucrose responsiveness in Drosophila.

Alteration in mean platelet volume and platicrit values in patients with cancer that developed thrombosis.

Mean platelet volume (MPV) is an indicator of thrombocyte volume and tendency to thrombosis can be mentioned in case of MPV elevation. Cancers are one of the important groups of thrombotic diseases. In the present study, MPV value was scrutinized in patients with cancer that developed thrombosis.

Treatment regimen with bevacizumab decreases mean platelet volume in patients with metastatic colon cancer.

The risk of thromboemboli is increased in patients with cancer, and this is precipitated by the chemotherapeutic agents. Bevacizumab is an anti-vascular endothelial growth factor monoclonal antibody and has an importance in the treatment of metastatic colon cancer. The association between bevacizumab, which is demonstrated to increase the risk of thromboemboli, and mean platelet volume (MPV), which is a marker of thrombocyte function, has been investigated within study.

Leptomeningeal carcinomatosis of gastric adenocarcinoma.

Gastric cancer is the third most common malignancy among gastrointestinal malignancies. With the advance of new treatments, overall survival in gastric cancer is extending, and metastasis to atypical sites is seen more commonly. Leptomeningeal metastasis is one such atypical metastasis for gastric cancer.

MR imaging in diffuse-type hepatocellular carcinoma with synchronous portal vein thrombi.

Background/aims: Diffuse or continuous multifocal tumors with accompanying portal vein thrombosis yield considerable changes in the magnetic resonance imaging findings of hepatocellular carcinoma. The overlapped imaging findings of these two co-existing pathologies may be confusing. We aimed to evaluate the magnetic resonance imaging findings of widespread hepatocellular carcinoma lesions complicated with portal vein thrombosis.

Frequencies of perianal fistula types using two classification systems.

Purpose: The aims of this study were to determine the frequencies of the perianal fistula subtypes according to the Parks and St. James's University Hospital (SJUH) classification systems and to evaluate the adequacy of these two systems for classifying and reporting perianal fistulas.

Materials And Methods: Magnetic resonance imaging examinations of 52 patients (44 men, 8 women) with perianal fistula were reviewed retrospectively.

Single-dose-dexketoprofen-induced acute kidney injury due to massive rhabdomyolysis.

A 70-year-old male patient was admitted complaining of weakness and pain in his arms and lower limbs. His serum creatine kinase and serum creatinine were markedly elevated (36,248 IU/L and 2.8 mg/dL, respectively).

MR angiography of esophageal mural veins in portal hypertension: a correlation with endoscopic grades of esophageal varices.

Background/aims: The esophageal mural veins are important for providing blood to the esophageal submucosal varices. The purpose of this study was to investigate any correlation between the diameters of esophageal mural veins as observed on routine contrast-enhanced magnetic resonance angiography and the endoscopic grades of esophageal varices in patients with portal hypertension.

Methods: The images of 57 patients with portal hypertension in whom magnetic resonance portography was performed were evaluated retrospectively.

Relationship between levels of serum creatinine and perirenal hyperintensity on heavily T2-weighted MR images.

Objective: To determine the frequency of perirenal hyperintensity on heavily T2-weighted images and to evaluate its relationship with serum creatinine levels.

Subjects And Methods: Axial and coronal single-shot fast spin-echo images which have been originally obtained for MR cholangiopancreatography in 150 subjects were examined by two observers individually for the presence of perirenal hyperintensity. The morphologic properties of perirenal hyperintensity (peripheral rim-like, discontinuous, polar) were recorded.

Hepatic venous outflow obstruction after hydatid cyst surgery: evaluation with contrast enhanced magnetic resonance angiography.

Introduction: The aim of this study is to present the contrast enhanced magnetic resonance angiography findings of hepatic venous outflow obstruction in patients in whom surgery had been performed for hepatic hydatidosis. No patient history of parasitic hepatic venous invasion or earlier hepatic venous outflow obstruction is present.

Materials And Methods: Four men and three women with a history of hydatid cyst surgery underwent contrast enhanced magnetic resonance angiography between April 2001 and June 2006.

Pelvic retroperitoneal angioleiomyoma mimicking a uterine mass.

Angioleiomyoma (vascular myoma) is a rare type of leiomyoma originating from smooth muscle cells and containing thick-walled vessels. There are only a few cases of retroperitoneal angioleiomyoma reported in the literature. Herein, we present the ultrasonography, magnetic resonance imaging and histopathological findings of an asymptomatic patient with a pelvic retroperitoneal angioleiomyoma which radiologically mimicked a uterine mass.

Post-treatment MRI findings of hepatocellular carcinoma.

In addition to surgery, ablative and transarterial therapies are widely accepted treatment options for hepatocellular carcinoma. Although post-treatment followup is usually done with both computed tomography and magnetic resonance imaging (MRI), MRI is found to be superior in detecting residual or recurrent tumors after treatment. Familiarity with post-treatment MRI findings is critical for the correct interpretation of these examinations, and for guiding further therapies.

The significance of the right hepatic artery originating from the superior mesenteric artery in patients with cavernous transformation of the portal vein.

Purpose: Dilatation of the hepatic artery in response to decrease in portal vein flow is known as hepatic arterial buffer response (HABR). In this study, the effect of HABR on variant hepatic arterial anatomy is investigated by analyzing the frequency of the right hepatic artery originating from the superior mesenteric artery (variant artery) and by determining the diameters of variant artery and common hepatic artery (CHA) in patients with cavernous transformation of the portal vein.

Materials And Methods: Forty-one patients who were referred for contrast-enhanced abdominal magnetic resonance angiography were retrospectively evaluated in two groups: group 1 (n = 15), cirrhotic patients with cavernous transformation of the portal vein; and group 2 (n = 26), cirrhotic patients without cavernous transformation of the portal vein.

Veins around the esophagus and the stomach: do their calibrations provide a diagnostic clue for portal hypertensive gastropathy?

Objective: We analyze whether calibrations of esophagogastric veins can be used as an indirect sign for the presence of portal hypertensive gastropathy (PHG).

Patients And Methods: The diameters of the left gastric, paraesophageal, and azygos veins were measured on magnetic resonance (MR) portograms of 57 patients with portal hypertension. The mean diameters of the above mentioned veins in patients with and without PHG were compared with Mann-Whitney U test.
