MR shows strength in imaging long bone fractures

MRI is useful in differentiating pathologic fractures from stress fractures in long bones when the clinical presentation of the fracture is misleading and radiography findings are also inconclusive. MRI is most sensitive to the presence of underlying bone marrow lesions and should be performed after radiography, according to researchers from the John Hopkins Medical Institutions in Baltimore.

Incidental focal findings on FDG PET/CT need follow-up endoscopy

Incidental focal colonic FDG uptake on PET/CT justifies performing a colonoscopy to detect malignant and premalignant lesions, French researchers have concluded. In a study of 20 patients with 21 areas of focal colonic uptake on routine PET/CT scans, the researchers found clinically significant lesions in 75% of the patients and 67% of the FDG findings.

Fetal mortality rate stays higher when early heart rates are lower

The mortality rate in early first-trimester pregnancies with slow fetal heartbeat is relatively high, even in cases in which follow-up ultrasound done within eight weeks shows normal heart rate, according to a retrospective study on the outcome of first-trimester pregnancies.

Ultrasound equivalent to x-ray for nasal fractures

Ultrasonography can be an alternative to radiography in diagnosing nasal fractures, according to researchers from Germany. The study team found no statistically significant difference between the two modalities in assessing the nasal pyramid for fractures.

MR, CT best to evaluate early tibial stress injury

MRI is the best technique to assess early tibial stress injury, but CT is the method of choice for detecting osteopenia, an early sign of fatigue damage of the cortical bone, according to a recent study by Italian researchers.

Gadolinium effective in CTA of pulmonary circulation

Gadolinium-based contrast agents, usually reserved for MR imaging, can provide diagnostic CT angiograms of pulmonary circulation with 16-detector-row CT, and can be used as an alternative to iodinated contrast in patients with contraindications for iodinated agents, according to researchers from France.

Small hepatic lesions mostly benign in female breast cancer patients

In female breast cancer patients, interval follow-up imaging rather than imaging workup or biopsy should be performed for hepatic lesions that are "too small to characterize" (TSTC) on CT. More so if it is stage 0 breast cancer and there are no clinical findings supporting suspicion of liver metastasis, according to recommendations by researchers from the Memorial Sloan-Kettering Cancer Center in New York City.

Fast spin-echo MRI unsuitable for meniscal tears

Fast spin-echo MRI turned in a lower sensitivity than conventional spin-echo for evaluating meniscal tears, according to a study out of Duke University in Durham, NC. As a result, the researchers recommended that musculoskeletal radiologists "abandon" fast-spin echo MRI in the meniscus.

Complex cardiothoracic surgery benefits from 3D imaging

Three-dimensional CT images are more than just pretty pictures when it comes to cardiothoracic surgery. Viewing 3D real-time images along with 2D ones can alter surgical plans for complex cases, and even increase a surgeon's confidence in the plan, according to a new study by researchers from the University of North Carolina (UNC) at Chapel Hill and the University of Alabama at Birmingham.
