Can a Deep Learning Algorithm Enhance Detection of Prostate Cancer Recurrence with Biparametric MRI?
September 26th 2023For patients who had previous radiotherapy for prostate cancer (PCa), researchers found that a biparametric MRI-based deep learning model demonstrated an 81.5 percent sensitivity rate for PCa recurrence in patients previously treated with external beam radiation treatment (EBRT) and 100 percent sensitivity in patients with greater than 34 ml in gland volumes.
New Multicenter Study Shows Viability of AI Tool for Detecting Central PE on CT
September 22nd 2023The Pulmonary Embolism (PE) Triage and Notification (PETN) module with RapidAI’s RapidPE platform reportedly demonstrated over 90 percent sensitivity and specificity rates for detection of central PE on computed tomography (CT), according to multicenter study findings presented at the 9th Annual Pulmonary Embolism Symposium.
Mammography-Based Deep Learning Model Facilitates Higher Breast Cancer Detection on Screening MRI
September 22nd 2023New research suggests the capability of a mammography-based deep learning model to identify women at high risk of breast cancer led to more than triple the cancer detection rate on breast MRI in comparison to traditional risk assessment tools.
Emerging PET/CT Agent May Enhance Diagnosis for Smaller Lesions of Clear Cell Renal Cell Carcinoma
September 20th 2023For cT1 renal masses < 4 cm and renal masses < 2 cm, the PET/CT agent 89Zr-DFO-girentuximab had respective sensitivity rates of approximately 85 percent and 96.7 percent for diagnosing clear cell renal cell carcinoma, according to research recently presented at the European Association of Nuclear Medicine (EANM) 2023 Congress.
Study Shows Significant Overutilization of Head and Neck CT Angiography in the ER
September 18th 2023Over 80 percent of head and neck computed tomography angiography (CTA) exams performed in the emergency department had no actionable findings for patients with non-focal neurologic complaints, and 67 percent of the exams were ordered by non-physician practitioners (NPPs), according to a newly published study.
Study: PET/CT Multivariate Model Enhances Accuracy for Diagnosing Prostate Cancer
September 13th 2023For men with PSA scores between 4 to 10 ng/mL, a multivariate prediction model that incorporates 68Ga-PSMA PET/CT had a 92.7 AUC for predicting clinically significant prostate cancer, according to newly published research.
FDA Clears AI Software for CT Detection and Triage of Obstructive Hydrocephalus
September 13th 2023Indicated for the triage and notification of obstructive hydrocephalus on non-contrast brain computed tomography (CT), the artificial intelligence (AI)-enabled software is reportedly the first radiology triage modality to obtain the Food and Drug Administration’s (FDA) Breakthrough Device Designation.
Large Mammography Study Suggests AI is Equivalent to Radiologists for Double Reading of Exams
September 11th 2023In a prospective study of over 55,000 women who had screening mammography, researchers found that double-reading by a radiologist and artificial intelligence (AI) was non-inferior to double-reading by two radiologists in detecting breast cancer.
Philips Unveils New Contrast-Enhanced Ultrasound Application for EPIQ Elite Device
September 8th 2023The Microvascular Imaging Super Resolution Contrast-Enhanced Ultrasound application reportedly leverages micro-bubble contrast media to provide enhanced spatial resolution for imaging of malignant lesions.
Study: 'All Men with PSAs Between 3 and 20 ng/mL Should Undergo MRI Before Biopsy'
September 7th 2023In a study of over 23,000 men who had PSA testing, researchers found that the adoption of pre-biopsy MRI resulted in a 21 percent decrease in negative biopsies and a 37 percent increase in the proportion of diagnosed Gleason score 7 to 10 prostate cancers.
Emerging PSMA PET Agent May Offer Improved Detection of Prostate Cancer
September 7th 2023The PSMA PET agent 64Cu SAR-bisPSMA detected a higher number of prostate cancer lesions and had a significantly higher SUVmax and SUVmean than 68Ga PSMA-11 PET/CT, according to initial data from a prospective multisite study presented at the recent Society of Nuclear Medicine and Molecular Imaging (SNMMI) conference.
Can AI Match Radiologist Assessment of Screening Mammography Exams?
September 5th 2023In separate test sets that included challenging mammography cases, researchers found that artificial intelligence (AI) demonstrated similar sensitivity and specificity for detecting breast cancer in comparison to assessments from over 500 clinicians.
