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.

Parallel processing gives boost to mammographyStrong evidence suggests that MR imaging is the most sensitive of all breast imaging techniques, including state-of-the-art mammography and high-frequency breast ultrasound. In contrast to mammography, the sensitivity and specificity of MR are not impaired by dense breast tissue, fibrocystic disease, or therapeutic interventions such as postsurgical scars or radiotherapy-induced fibrosis.

MSCT venography finds cerebral thrombosesDural sinus and cerebral venous thromboses (CVT) are difficult to diagnose. Symptoms are often nonspecific and may evolve slowly, and anatomic variations can further complicate diagnostic decision making. Unilateral aplasias of the transverse or sigmoid sinus, frontal agenesis of the superior sagittal sinus, and high partitions of the transverse sinus are common pitfalls in the diagnosis of CVT.
