Radiology ReviewMRIMRI features of larger lesions predict malignancy in cirrhotic liver(Radiology Review) MRI T1-weighted hypointense lesions on unenhanced in-phase images and T2-weighted hyperintensity or arterial hypervascularity are highly suggestive of malignancy in patients with liver cirrhosis, according to a study published in the American Journal of Roentgenology.June 12, 2007Image-Guided SurgeryUS-guided needle aspiration offers effective, low-cost treatment for liver abscessesTrial percutaneous needle aspiration of multiple pyogenic liver abscesses, under ultrasound guidance, should be performed prior to catheter drainage or surgery, according to researchers from Italy. Because of its low-cost, real-time nature, and mobility, ultrasound is more versatile than CT guidance, the group states.January 4, 2007Image ProcessingPhase imaging with MPR improves MDCT of pancreatic cancerFor evaluating pancreatic adenocarcinoma using triple-phase multidetector-row CT (MDCT), a combination of pancreatic parenchymal and portal venous phase imaging is essential and appropriate, according to radiologists in Japan.January 3, 2007UltrasoundAppendiceal involvement in Crohn's disease: Grayscale sonography and color Doppler flow features(Radiology Review) Sonography and color Doppler sonography may be useful for differentiating acute appendicitis from appendiceal involvement in Crohn's disease, according radiologists from Spain.June 19, 2006CTHemodynamic CT studies of stage T1 lung cancer help predict hilar or mediastinal nodal metastasis(Radiology Review) Korean radiologists found that the peak and net enhancement and maximum enhancement ratio on dynamic CT can be used to predict hilar or mediastinal nodal metastasis in patients with stage T1 lung cancers.June 19, 2006UltrasoundContrast-enhanced US useful for differentiating focal liver lesions(Radiology Review) All three vascular phases should be assessed when sonographic contrast agents are used to differentiate benign from malignant focal liver lesions, according to researchers from Spain. They evaluated the accuracy of tumoral vascularity display in liver tumors using contrast-enhanced sonography.January 18, 2006MRIChemical shift MRI improves detection of adrenal adenomas(Radiology Review) Whether a coexisting adrenal mass is an adenoma or metastasis affects treatment of extra-adrenal primary tumors, according to researchers from Turkey. They report in the American Journal of Roentgenology that chemical shift MRI can help differentiate adrenal adenomas from nonadenomas and metastases.January 18, 2006UltrasoundEarly postoperative US predicts liver transplant complications(Radiology Review) The hepatic artery resistive index can predict vascular and nonvascular complications in adult liver transplant patients, according to a study published in the American Journal of Roentgenology. The authors highlight the importance of early detection of hepatic artery stenosis or thrombosis with ultrasound to enable timely revascularization.January 5, 2006MRIFour MRI signs diagnose radial meniscal tears preoperatively(Radiology Review) Radiologists at Duke University Medical Center in Durham, NC, recently assessed the prevalence of radial meniscal tears at arthroscopy and whether MR imaging could accurately detect radial tears prior to surgery. Their retrospective study was published in the American Journal of Roentgenology.December 22, 2005UltrasoundUS-guided core biopsy of nonpalpable breast lesions identifies focal fibrosis(Radiology Review) Korean radiologists recently used the Breast Imaging Reporting and Data System (BI-RADS) to evaluate the frequency, imaging features, and clinical relevance of focal fibrosis of the breast diagnosed by a sonographically guided core biopsy of nonpalpable lesions.October 19, 2005Previous PagePage 2 of 6Next PageTop StoriesRadiation Oncology/TherapyASTRO applauds new legislation on radiation therapy paymentsThe American Society for Radiation Oncology (ASTRO) applauded the introduction of legislation in Congress on May 15 that could radically change the way Medicare pays for radiation therapy.MRILow sexual desire manifests as dimorphic brain processing on fMRIPractice ManagementX-ray vision: The complexities of radiology revenue cycle managementWomens ImagingCan positive leadership combat burnout among radiologists?Sponsor ContentIMV’s Oncology in Diagnostic Imaging Market Outlook Report
