Abdominal CT Study Shows 20 Percent Reduction in Iodine Contrast with Photon Counting CT
In addition to a 20.1 percent reduction in iodine load, photon-counting CT offered higher signal-to-noise and contrast-to-noise ratios than energy-integrating detector CT in a new study.
Comparative Study Evaluates AI Products for Detecting Tuberculosis on Chest X-Rays
At a 90 percent threshold for sensitivity, Lunit’s Insight CXR and the Nexus CXR software from Nexus demonstrated the highest specificity rates for tuberculosis (TB) detection in a patient population with a high prevalence of TB and HIV.
Prostate biopsy reclassification was 2.3 times more likely with PI-RADS > 4 lesions in patients in comparison to those with PI-RADS 1-3 lesion assessments, according to new MRI research involving nearly 1,500 men with low-risk and favorable intermediate risk for prostate cancer.
External validation testing revealed a deep learning combination of breast MRI, ultrasound and clinical factors had a 10 percent higher AUC for predicting axillary lymph node metastasis than sole use of MRI- or ultrasound-based deep learning models in patients with breast cancer.
What New Computed Tomography Research Reveals About Predicting Diabetes and Cardiometabolic Risks
Automated CT-derived assessments may provide stronger stratification of diabetes and cardiometabolic risks than conventional predictive models, according to a new study of over 32,000 adults in Korea.
Can Targeted PSMA PET/CT-Guided Radiotherapy Have an Impact for Oligometastatic Prostate Cancer?
Emerging research revealed a median progression-free survival of 16.4 months and a 29-month mean freedom from a new line of systemic therapy for the use of PSMA PET/CT guided, metastasis-targeted radiotherapy for patients with oligometastatic castration-resistant PCa.
Emerging PET Imaging Agent Gets FDA’s Breakthrough Therapy Designation for Cardiac Amyloidosis
Reportedly the only imaging agent to garner a breakthrough therapy designation for cardiac amyloidosis, 124I-evuzamitide has demonstrated robust sensitivity for the condition as well as a favorable safety profile.
CMS Approves NTAP Reimbursement for CT-Based AI Triage Software for Obstructive Hydrocephalus
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.
Current Concepts in Preventing and Managing Contrast Media Extravasation
August 1st 2024While 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.
Interventional Radiology-Led Study Shows Benefits of CT-Guided Cryoablation for Soft Tissue Sarcoma
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.
What New Research Reveals About Digital Mammography and Digital Breast Tomosynthesis
Digital breast tomosynthesis (DBT) had a significantly higher cancer detection rate (CDR) in comparison to two consecutive post-DBT rounds of digital mammography, according to a new secondary analysis of the Malmo Breast Tomosynthesis Screening Trial (MBTST).
Study: Photon Counting CT Reduces Radiation Exposure by 44 Percent for Kidney Stone Detection
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.
