Effective use of abdominal CT can save lives in emergency setting
March 10th 2010It is widely accepted that reducing time from admission to definitive care saves lives, but usually imaging is one of the major sources of delays. This means radiologists play a vital role in prioritizing patients and selecting the correct modality.
Diffusion-weighted MR looks to add new biomarker for oncologic imaging
March 5th 2010MR developments over recent years have allowed researchers to explore water molecule motion between cells using diffusion-weighted imaging to indirectly measure cellular density within a tissue. This has provided a new and continuously evolving tool in oncologic imaging for lesion detection, characterisation, and therapy assessment.
Indian radiologists wrestle with law to prevent imaging-based sex-selective abortions
February 12th 2010Sixteen years on from implementation of the Pre-Conception (PC) and Pre-Natal Diagnostic Techniques (PNDT) Act, burdensome bureaucracy penalizes many law-abiding radiologists in India. Furthermore, rather than preventing them, the act has driven up the price of illegal sex selection services. Meanwhile, registered ultrasound clinics face heavy fines for minor infringements.
New training course focuses attention on urinary tract
March 6th 2009CT urography with multislice technology has a very high spatial resolution for imaging the urinary tract. It can detect tiny urothelial tumors inside the intrarenal collecting system and ureter, potentially avoiding the need for more invasive endourologic procedures. MR urography is preferred for some patients, however.
Dutch doctors tout ultrasound for appendicitis in children, caution against CT overuse
March 10th 2008The number of CT scans performed in the pediatric abdomen in the U.S. is high compared with Europe, possibly because doctors fear legal action in the case of a missed pathology or disease. Rather than using CT for appendicitis, many doctors in the Netherlands still prefer to use ultrasound to visualize the swollen, fluid-filled, or normal appendix.
Report from ECR: Experts pinpoint benefits of hybrid systems in cancer management
March 16th 2007Correct diagnosis of tumor character and stage is fundamental to lung cancer therapy planning. It is vital to determine as soon as possible whether patients are likely to respond to treatment, but evaluating indeterminate solitary pulmonary nodules continues to challenge radiologists.
Experts pinpoint benefits of hybrid systems in cancer management
March 13th 2007Correct diagnosis of tumor character and stage is fundamental to lung-cancer therapy planning, but evaluating indeterminate solitary pulmonary nodules (SPNs) continues to challenge radiologists. In addition, it is vital to determine as soon as possible whether patients are likely to respond to treatment.
Hardware, software advances give fMRI a place in abdominal imaging
March 13th 2007Technical advances in MRI have paved the way for functional imaging of the abdomen, moving beyond simple morphological evaluation of disease and in some cases proving superior to multislice CT. With quantitative imaging tools at their disposal, radiologists are rethinking what they need to visualize with MR to answer new clinical questions.
Head and neck reports must combine accurate descriptions with foresight
March 10th 2007In treating an underlying problem in the head and neck, potential complications must be identified and graded in the radiologist’s report for correct follow-up. Radiologists may be able to solve a clinical problem directly with a single approach such as ultrasound. But other modalities must be used when ultrasound fails due to the depth of a lesion or air within the lumen, making evaluation of the head and neck complex, according to researchers from Italy, Austria, and Switzerland.
New techniques promise better detection of prostate cancer
March 10th 2007Ultrasound techniques that are improving prostate cancer detection, grading, and staging are useful in men presenting with an elevated level of prostate specific antigen. They offer therapeutic strategies and may avoid the need for prostatectomy. In the future, surgery may not be the number one treatment choice, according to speakers at a special focus session on imaging in patients with elevated PSA levels.
