Breast-specific gamma scans monitor chemo
Breast-specific gamma imaging is highly accurate in monitoring the response of breast cancers to neoadjuvant chemotherapy, according to a study presented at the American Society of Breast Surgeons' annual meeting in Las Vegas.
Breast-specific gamma imaging is highly accurate in monitoring the response of breast cancers to neoadjuvant chemotherapy, according to a study presented at the American Society of Breast Surgeons' annual meeting in Las Vegas.
In their 12-subject study, George Washington University Hospital researchers found gamma imaging accurately establishes tumor size within 5 mm after neoadjuvant chemotherapy. The pathologic size ranged from 2.6 cm to 2 mm postchemotherapy. In addition, the correlation coefficients are superior to those of other modalities, including physical exam, mammography, ultrasound, MRI, and FDG-PET, according to the authors.
The researchers compared gamma camera breast tumor images postchemotherapy with pathologic size at excision. They found the gamma imaging accurately reflected tumor size in all 12 patients.
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.
