Communication failures present big legal riskA 55-year-old man with cough and mild fever presented to his internist in Colorado for evaluation on a Thursday afternoon. The doctor sent the patient across the street to the hospital for a chest x-ray. Radiographs were obtained but set aside to be matched with old films. They were not read by the radiologist until Saturday morning. Unfortunately, the written report was not delivered to the referring doctor until the following Tuesday. The patient had died the night before of Legionella pneumophila. When asked why he hadn't called the results to the doctor, the radiologist replied that he had tried but couldn't get through. The case was settled for an undisclosed sum, with settlements paid by the internist, the radiologist, and the local hospital.

Cardiac CTA should stay with radiologistsAs a practicing radiologist for 28 years, I was happy to see the Point/Counterpoint repartee between Dr. Carter Newton and Dr. David Dowe in Diagnostic Imaging (September 2006, pages 24 and 25) regarding cardiac CT angiography. It's time the radiology community and the medical community at large understand the difference between real imaging professionals and doctors who believe that cardiac imaging is some type of divine entitlement.

Image Guidance: Interventions multiply for liver tumor therapyPercutaneous options for hepatic tumor treatment are expanding, even as the incidence of primary and metastatic liver tumors continues to rise. While surgery remains the treatment of choice for patients meeting criteria for resection, results from minimally invasive treatments have exceeded those obtained with conventional chemotherapy or radiation, and it is possible that one or more of these techniques may soon vie with surgery as a treatment of choice for patients with liver tumors.

Lung ablation shows promising results in safety and efficacyLung carcinoma remains the leading cause of cancer death in the U.S. Over the past decade, lung cancer death rates have more than quadrupled, from 5.4 to 29.4 per 100,000.1 The American Cancer Society estimates that in 2005 the number of lung cancer deaths will rise to 163,510-90,490 men and 73,020 women-accounting for 28% of all cancer-related deaths. The number of newly diagnosed lung cancers will rise to 172,570, or 93,010 new cases in men and 79,560 in women.2 Nearly 60% of those diagnosed with lung cancer die within one year of their diagnosis and nearly 75% within two years.2

PET/CT imaging distinguishes potentially treatable dementiasFlorida is home to a large aging population at risk for dementia. Palm Harbor, not far from St. Petersburg and Tampa, is also close to a retirement town. There are many nursing homes and extended care facilities throughout the region, and the reimbursement climate includes sizable expenditures for Alzheimer's disease care.

Diffusion-weighted MRI moves beyond brain to other body partsMR imaging can be used for many applications in oncology. Its main roles in cancer imaging are determining locoregional tumor extent, characterizing tumors, and monitoring treatment. MRI, like CT, relies on morphological criteria for lesion differentiation. This reliance, however, can make it difficult to detect small cancerous deposits and to differentiate tumor recurrence from treatment-induced tissue changes.

Multiple modalities explore schizophreniaNeuroimaging research has contributed enormously to our understanding of structural and functional differences between the brains of people with schizophrenia and those of healthy people. Imaging now offers insights into how drugs used to treat schizophrenia work as well as the genetic mechanisms that lie at the root of these disorders.

Cardiology PACS must produce moving imagesTensions between radiology and cardiology in the field of cardiac imaging have persisted for decades. The 1970s and 1980s were rife with turf battles over interventional angiography, echocardiography, and cardiac SPECT. More recently, cardiac MRI and CT have been the focus of intense debate about who is best qualified to perform and interpret these scans.

Patient dose concerns loom larger: need, education, licensure, is our answerA physician, who at the time was the principal doctor of a major medical clinic, once approached me about radiation dose issues and asked me to compare a chest x-ray to a chest and abdomen CT scan. I was prepared, having dealt with similar concerns expressed by other medical practitioners, and explained briefly how it can vary greatly and how the potential health hazards are weighed against the benefits. It was not the first time I had an inquiry about dose-saving techniques from the medical community or from patients. I started realizing how more and more the general public is being affected by media coverage and how the medical community should be able to react.

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.

Carotid stenting offers new interventional practice optionAs carotid artery stenting becomes an accepted tool for stroke prevention in appropriate patients, interventional radiologists and neuroradiologists are determining where this procedure fits into their practice. Some have already developed an active carotid artery stenting practice, but others are looking for resources to help them begin to offer this service. Consideration of many elements is required to offer a high-quality service.
