Interventional Radiology-Led Study Shows Benefits of CT-Guided Cryoablation for Soft Tissue Sarcoma
August 1st 2024In 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
July 31st 2024Digital 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
July 31st 2024New 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.
Techsomed Launches Ultrasound-Based Software Suite for Liver Tumor Ablation Therapy
July 29th 2024Featuring the previously FDA-cleared BioTraceIO Vision and BioTraceIO Precision modalities, the BioTrace software suite combines real-time ultrasound guidance and advanced AI technology to help bolster outcomes with liver tumor ablation therapy.
CT-Based Radiomic Model Shows Promise for Pre-Op Staging of Clear Cell Renal Cell Carcinoma
July 27th 2024An emerging diagnostic model incorporating radiomic features from intratumoral and peritumoral regions exhibited a 29 percent higher AUC and 77 percent higher sensitivity rate than a clinical model for predicting the grading of clear cell renal cell carcinoma, according to recent research.
MRI-Based AI Radiomics Model Offers 'Robust' Prediction of Perineural Invasion in Prostate Cancer
July 26th 2024A model that combines MRI-based deep learning radiomics and clinical factors demonstrated an 84.8 percent ROC AUC and a 92.6 percent precision-recall AUC for predicting perineural invasion in prostate cancer cases.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
Systematic Review: PET/MRI May be More Advantageous than PET/CT in Cancer Imaging
July 18th 2024While 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.
Study Assesses Amyloid PET/MRI Combination in Detection of Alzheimer’s Disease
July 15th 2024Emerging research revealed that a machine learning combination of amyloid beta PET and structural MRI demonstrated an 89 percent AUC in differentiating between older healthy patients and those with Alzheimer’s disease.
A Victory for Radiology: New CMS Proposal Would Provide Coverage of CT Colonography in 2025
July 12th 2024In newly issued proposals addressing changes to coverage for Medicare services in 2025, the Centers for Medicare and Medicaid Services (CMS) announced its intent to provide coverage of computed tomography colonography (CTC) for Medicare beneficiaries in 2025.
Study: Use of Preoperative MRI 46 Percent Less Likely for Black Women with Breast Cancer
July 11th 2024In the study of over 1,400 women with breast cancer, researchers noted that Black women with dense breasts or lobular histology were significantly less likely to have preoperative MRI exams than White women with the same clinical characteristics.
Can AI Facilitate Effective Triage for Supplemental Breast MRI After Negative Mammography Screening?
July 10th 2024The AISmartDensity software facilitated a cancer detection rate (CDR) with breast MRI that was nearly four times higher than the CDR previously reported in trials involving traditional breast density assessment.
Study: PSMA PET/CT More Advantageous than MRI for Locoregional Staging of Prostate Cancer
July 8th 2024For men with prostate cancer, new research demonstrates that 18F-PSMA-1007 PET/CT is 17 percent more accurate than mpMRI at identifying the final pathological tumor stage and 12 percent more accurate in detecting extracapsular extension.
