U.K. specialists want relevancy, detail in radiology reports
April 10, 2009 -- Radiology reports that are most beneficial include clinical comments and are presented in a consistent, easy-to-read tabular format, according to a survey of physicians ordering radiology procedures from a community hospital in northwest England.
Adding chest CT to VC not cost-effective, study finds
April 7, 2009 -- Adding a chest CT scan to screening virtual colonoscopy isn't cost-effective in a cohort of average-risk patients, a new model-based analysis concluded. Although the additional anatomic coverage increased the clinical efficiency of CT-based screening, the combined test would not detect enough serious pathology to cover the costs of detection and follow-up of disease.
MDCT holds promise for advanced osteoporosis scan
April 6, 2009 -- CT could become an important player in the emerging field of structural bone assessment, according to researchers from Berlin and San Francisco. They believe the modality is capable of evaluating trabecular structures from the extremities to the vertebrae, outperforming even high-resolution peripheral quantitative CT (HR-pQCT) in some conditions.
Virtual colonoscopy CAD finds most cancers
April 3, 2009 -- A computer-aided detection (CAD) algorithm designed to find polypoid lesions of the colon also does fairly well at finding frank cancers, researchers from the U.K. concluded. But sensitivity varies depending on the system settings and the quality of the prep.
Single-entry APBI offers flexibility in treating breast cancer
April 3, 2009 -- Until recently, accelerated partial-breast irradiation (APBI) was not an option for most women with small breasts or a tumor located close to the chest wall and lung or the surface of the skin. The introduction of multicatheter single-entry brachytherapy devices, however, is beginning to change the situation.
Digital tomo works well for some kidney, ureteral stones
April 2, 2009 -- A new study by Belgian researchers indicates that digital tomosynthesis could be useful for assessing ureteral and kidney stones, particularly for screening patients prior to CT. But the digital radiography technique has different levels of accuracy depending on the location and size of stones.
CT for brain metastasis unnecessary after PET/CT
April 2, 2009 -- A CT scan is often ordered to find brain metastases in lung cancer patients. But if a whole-body PET/CT scan is already available from the original workup, there's no need for a dedicated CT scan, according to researchers from Belgium, who found that the CT portion of the PET/CT scan is enough for the initial diagnosis.
ACC study: Coronary CTA tops other tests for long-term prognosis
April 2, 2009 -- ORLANDO - Coronary CT angiography (CCTA) is better than conventional risk scores and calcium scoring at predicting the long-term prognosis of patients with obstructive coronary artery disease, researchers reported at the annual meeting of the American College of Cardiology (ACC).
Follow-up ultrasound aids in evaluating new lesions from breast MR
April 1, 2009 -- Performing a "second-look" ultrasound study can offer value for evaluating suspicious incidental lesions discovered on breast MRI, according to a pair of Italian studies presented at the 2009 European Congress of Radiology.
ACC study: Sequential CT delivers less radiation, good image quality
March 31, 2009 -- ORLANDO - Using a sequential scanning mode during coronary CT angiography studies cuts radiation dose in half without impairing image quality compared to standard retrospective spiral data acquisition, according to a study presented at this week's American College of Cardiology (ACC) meeting.
