Paging through radiology literature stirs remembrance of things pastI recently completed a task that we expect will lead to a more refined search engine for the Diagnostic Imaging Web site and those of our sister publications at CMPMedica. The project required perusing some 400-plus articles in the radiology literature from the past 30 years, covering every conceivable subcategory, and tagging those that best define each clinical application and modality. It involved some tedious parsing of wheat from chaff but provided ample opportunity for reflection on how far radiology has come.

Kidney tumor ablation treats nonsurgical candidatesOver 35,000 new cases of renal cell carcinoma occurred in the U.S. in 2001,1 most of them detected as incidental imaging findings on CT, MR, or ultrasound.2,3 Since most of these tumors are relatively small when detected, the classic clinical triad of flank pain, hematuria, and palpable mass is now rarely encountered. Many of these incidentally discovered RCCs are also slow growing. Bosniak et al showed that RCCs smaller than or equal to 3.5 cm grow at an average rate of 0 to 1.1 cm/year (mean 0.36 cm/year).4

SPECT/CT and PET/CT detect stenosis, ischemia in one examNoninvasive cardiac imaging plays an important role in diagnosis and management of patients with known or suspected coronary artery disease. Traditionally, the degree of coronary artery stenosis has been evaluated by catheter coronary angiography, and the hemodynamic significance of the stenosis evaluated by a functional test, such as rest and stress myocardial perfusion scintigraphy using SPECT or PET.

Report from ASCO: Studies reveal pros and cons of breast MRIMRI’s changing status as an instrument for breast cancer diagnosis and evaluation was apparent last month at the 2008 American Society of Clinical Oncology meeting. One study suggested that MR’s growing popularity for treatment planning may had led to more mastectomies, and another trial added to growing evidence about its ability to identify metastatic lymph nodes.
