While cone-beam computed tomography (CBCT) demonstrated high pooled sensitivity and specificity rates for intraparenchymal hemorrhage in the systematic review, researchers noted higher false-negative rates for subarachnoid and intraventricular hemorrhages.

Utilizing low-dose computed tomography (CT) scans for a cohort of over 10,000 non-smokers, researchers found that over 11 percent of study participants had clinically relevant lung nodules.

The researchers found that (18F)FDG PET/MRI had a 17 percent higher pooled sensitivity rate for cardiac sarcoidosis in contrast to (18F)FDG PET/CT.

The first radiology triage modality to garner a Breakthrough Device Designation from the FDA, Annalise-Obstructive Hydrocephalus has reported sensitivity and specificity rates of 97.5 percent and 95.3 percent respectively.

While contrast media extravasation is a rare complication, there can be varying degrees of severity. Accordingly, this author reviews possible causes of this complication, prevention principles and pertinent considerations in addressing this complication when it does occur.

In a study involving 217 percutaneous cryoablation procedures for treating recurrent or metastatic soft tissue sarcoma in 141 patients, researchers noted an 86 percent rate of local progression-free survival and a 2 percent complication rate.

New research shows that photon-counting computed tomography (PCCT) at an effective dose of 0.79 mSv provided significantly higher signal-to-noise ratios for urinary calculi (kidney stone) detection than energy-integrating detector CT at 1.39 mSv.

Emerging research suggests CT radiation dosing of 50 mSv or greater is associated with higher mortality at two years but nearly half of those patients were alive 10 years later.

While PET/MRI and PET/CT had comparable sensitivity for patient-level regional nodal metastases and lesion-level recurrence, the authors of a systematic review noted that PET/MRI had significantly higher accuracy in breast cancer and colorectal cancer staging.

Researchers found that mpMRI was 18 percent more accurate than dual-energy CT (DECT) for T1 staging and 19 percent more accurate for N3 staging of gastric cancer.
