While a large retrospective study found that interstitial lung abnormalities (ILAs) were evident on 1.7 percent of computed tomography (CT) scans, researchers found that 43.9 percent of ILAs, including fibrotic ILAs, were not reported.
Study Assesses Lung CT-Based AI Models for Predicting Interstitial Lung Abnormality
September 6th 2024A machine-learning-based model demonstrated an 87 percent area under the curve and a 90 percent specificity rate for predicting interstitial lung abnormality on CT scans, according to new research.
New Study Identifies Key Computed Tomography Findings for Post-Op Recurrence of Pancreatic Cancer
August 22nd 2024For patients who had post-op recurrence after a Whipple procedure for pancreatic ductal adenocarcinoma (PDAC), between 80 to 86 percent of follow-up CT exams revealed new or increased soft tissue.
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
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.
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.
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.
