A Case for Decision Support of Imaging ServicesWhile we agree that both approaches can help manage utilization rates of imaging and reduce health care costs, we beg to strongly differ that prior notification is the better option. We have hard facts that indicate decision support is better for not only patients, but providers, health plans, and our nation.

Primary Peritoneal MesotheliomaA 56-year-old Vietnam veteran man was admitted with a three-day history of worsening abdominal pain progressing into an acute abdomen. He had past medical history of Hepatitis C, diabetes mellitus, high blood pressure and chronic abdominal pain of unknown etiology. There was no gross bowel pathology by upper endoscopy or colonoscopy early the year of admission.

CT and MRI help evaluate adrenal gland disordersThe adrenal glands are paired retroperitoneal endocrine organs. They are thin, inverted Y- or V-shaped soft tissue structures and have flat or concave margins. The vertical length of each gland may be anywhere from 2 to 4 cm. Their “limbs” are approximately 0.4 cm thick in axial cross-section, which is roughly as thin as the adjacent diaphragmatic crus.

MR, CT imaging offer answers to questions about renal massThe widespread use of cross-sectional imaging techniques means that renal masses are now a common incidental finding. The term renal mass covers a diverse group of pathologic entities, including inflammatory, vascular, and benign tumors and neoplastic lesions. Most renal masses are simple cysts that can be characterized easily and require no treatment or follow-up. But approximately 25% to 40% of all renal cell carcinomas are diagnosed after the unexpected discovery of a renal mass.1 Around 85% of these renal cancers will be adenocarcinomas. Most of the others will be transitional cell carcinomas of the renal pelvis.

Anatomic, functional imaging collaborate in cancer detectionSeveral oncologic imaging modalities have evolved significantly since CT was developed in 1973. Although CT provides a noninvasive method for evaluating cancer patients, first-generation scanners were limited in their speed of data acquisition and spatial resolution. Current multislice CT scanners can evaluate a patient completely, with exquisite anatomic detail, in as little as 15 to 30 seconds.

3-D CT angiography aids in liver surgery planningCT angiography is a powerful technique for assessing visceral arteries that may obviate catheter angiography. A quality CTA with good contrast timing, minimal visual noise, and proper 3D postprocessing techniques provides excellent detail of arterial anatomy. CTAs are particularly important for patients with unresectable liver metastases, in whom regional chemotherapy is an alternative treatment option.

Innovative physics boosts MRI speed, cuts CT doseRecent advances in fast imaging have provided radiologists with tools for simplified scanning and improved diagnosis. Real-time diagnostic capability gives radiologists unprecedented freedom to uncover pathology and measure its extent and severity. Multislice CT captures hundreds of slices per second, freezing motion and creating mammoth files of data for reconstruction into diagnostically relevant renderings of organs, bone, vessels, and disease.

MRI expands options in lung assessmentPulmonary embolism is a common, potentially life-threatening condition.1 Diagnosing PE remains a major challenge because typical symptoms such as dyspnea, tachycardia, acute chest pain, and syncope are unspecific and may not be present in all patients. Imaging therefore plays a pivotal role in establishing a diagnosis.2

MRI proves clinical value in lung cancerNon-small cell lung cancer is the leading cause of cancer-related deaths in women and men in the Western Hemisphere. Surgical resection remains the mainstay of therapy in disease at stages I and II, and this treatment has an acceptable morbidity and mortality rate. Imaging is needed for effective treatment planning and accurate diagnosis, including preoperative assessment of resectability.
