Computerized Tomography derived psoas muscle indices in a healthy young population in the United States.

Objective: Psoas muscle metrics from diagnostic computerized tomography (CT) scans are emerging as clinically relevant biomarkers. Most muscle metrics from the US population are from older cohorts with co-morbidities. Published reports from a young or healthy population in the United States on psoas muscle metrics optimized for age, body mass index (BMI), and sex are lacking.

Evaluation of Adaptive Statistical Iterative Reconstruction-V Reconstruction Algorithm vs Filtered Back Projection in the Detection of Hypodense Liver Lesions: Reader Performance and Preferences.

Objective: The aim of the study was to evaluate diagnostic accuracy and readers' experience in the detection of focal liver lesions on computed tomography with Adaptive Statistical Iterative Reconstruction-V (ASIR-V) reconstruction compared with filtered back projection (FBP) scans.

Methods: Fifty-five patients with liver lesions had FBP and ASIR-V scans. Two radiologists independently reviewed both sets of computed tomography scans, identifying and characterizing liver lesions.

MUC1 and HIF-1alpha Signaling Crosstalk Induces Anabolic Glucose Metabolism to Impart Gemcitabine Resistance to Pancreatic Cancer.

Poor response to cancer therapy due to resistance remains a clinical challenge. The present study establishes a widely prevalent mechanism of resistance to gemcitabine in pancreatic cancer, whereby increased glycolytic flux leads to glucose addiction in cancer cells and a corresponding increase in pyrimidine biosynthesis to enhance the intrinsic levels of deoxycytidine triphosphate (dCTP). Increased levels of dCTP diminish the effective levels of gemcitabine through molecular competition.

Duodenal gangliocytic paraganglioma with lymph node metastases: A case report and comparative review of 31 cases.

Gangliocytic paraganglioma (GP) is a rare tumor of uncertain origin most often located in the second portion of the duodenum. It is composed of three cellular components: Epithelioid endocrine cells, spindle-like/sustentacular cells, and ganglion-like cells. While this tumor most often behaves in a benign manner, cases with metastasis are reported.

Does endorectal coil MRI increase the accuracy of preoperative prostate cancer staging?

Introduction: We sought to investigate the association of preprostatectomy magnetic resonance imaging (MRI) and surgical pathologic findings in patients with prostate cancer.

Materials And Methods: All patients with prostate cancer and preprostatectomy MRI available between 2002 and 2015 were included. Age, prostate-specific antigen at diagnosis, Gleason score at biopsy, MRI technique, radiology report suggestive of prostate cancer, extraprostatic invasion and seminal vesicle involvement, lymphadenopathy and final pathology report were retrospectively reviewed.

Cystic Cervicitis: A Case Report and Literature Review of Cystic Cervical Lesions.

We present a case of a 30-year-old woman who, while undergoing infertility evaluation, was found to have a large cystic cervical mass, shown to be cystic cervicitis on cervical cone biopsy. Differential diagnosis for benign cystic cervical lesions includes Nabothian cysts, tunnel cluster, endocervical hyperplasia, and cervicitis, whereas cystic cervical malignancies include adenocarcinoma and adenoma malignum. While it is crucial to differentiate benign from malignant lesions, imaging characteristics often overlap and may not provide a specific diagnosis.

MR imaging of the female pelvis at 3T.

The recent development of the transmit-receive body coil and the dedicated torso phased-array radio frequency receive coil for 3.0T MR imaging systems has promoted a move toward higher-field, whole-body MR imaging, including pelvic MR imaging. The female pelvis is an anatomic area that may benefit particularly from the advantages of high-field systems.
