For the detection of obstructive coronary artery disease (CAD), stress cardiovascular magnetic resonance imaging (MRI) demonstrated a sensitivity rate of 81 percent and a specificity rate of 86 percent, according to a meta-analysis of 64 studies and data from 74,470 patients with stable chest pain.
The Path of Least Resistance: Make it a Road Less Traveled in Radiology
June 5th 2023Whether it’s attempting to get appropriate clinical histories from referring physicians or getting a tech to split up a multiphasic contrast study into separate image series, consistently striving to fight the good fight for optimal image interpretation is worth the effort.
For patients with residual or recurrent grade 2 isocitrate dehydrogenase (IDH)-mutant gliomas, magnetic resonance imaging (MRI) revealed that daily dosing of vorasidenib, an inhibitor of mutant IDH1 and IDH2 enzymes, led to a median progression-free survival of 27.7 months in comparison to 11.1 months in a placebo group, according to new research presented at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.
What a New Meta-Analysis Reveals About CT Diagnosis of COVID-19
In a review of patient data from 42 countries, researchers found that standardized typical findings on computed tomography (CT) for COVID-19 had a pooled sensitivity rate of 70 percent and a pooled specificity rate of 90 percent.
Large Study Shows Mixed Results in Comparison of DBT and Digital Mammography
In a large retrospective study involving over 523,000 digital breast tomosynthesis (DBT) exams and over one million digital mammography (DM) exams, researchers found that DBT was associated with significantly lower recall rates but showed no advantage over DM in the diagnosis of interval or advanced breast cancer.
FDA Approves New PSMA PET Agent POSLUMA for Prostate Cancer Imaging
Reportedly the first FDA-approved PSMA PET agent with proprietary radiohybrid technology, POSLUMA can be utilized for positron emission tomography (PET) scans of prostate-specific membrane antigen (PSMA) positive lesions in men with prostate cancer and suspected metastasis, and those with suspected prostate cancer recurrence based on an elevated serum prostate-specific antigen (PSA) level.
Can Photon-Counting CT Have an Impact in Diagnosing Congenital Heart Defects in Young Children?
Photon-counting computed tomography (PCCT) significantly increased the signal-to-noise ratio (SNR) and the contrast-to-noise ratio (CNR) in comparison to dual-source CT (DSCT) at similar radiation dosing, according to a new study of over 100 children with suspected congenital heart defects.
Mammography Study Finds No Significant Link Between Breast Density and Breast Cancer Prognosis
In a study involving over 1,100 women diagnosed with breast cancer, researchers found that 48.7 percent of women alive or dead from other causes at a median follow-up of 11.7 years had moderately dense breasts. They also found that 46 percent of women who died from breast cancer at a median-follow-up of 5.3 years had moderately dense breasts.
