MRI predicts lymph node involvementin cervical cancer better than CT
MRI can predict the presence of lymph node involvement in women with early invasive cervical cancer, according to a study in Gynecologic Oncology.
MRI can predict the presence of lymph node involvement in women with early invasive cervical cancer, according to a study in Gynecologic Oncology.
The ACRIN/GOG study enrolled 208 patients with biopsy-proven invasive cervical cancer. Each patient was imaged with CT and MRI prospectively by one onsite radiologist and retrospectively by four independent offsite radiologists. All were blinded to surgical, histopathological, and other imaging findings.
The researchers found lymphatic metastases in 34% of women; 13% had common iliac nodal metastases, and 9% had paraortic nodal metastases. Accurate prediction of histologic lymph node involvement based on tumor size was higher for MRI than for CT, they found.
The study was conducted by Dr. Donald G. Mitchell and colleagues at Thomas Jefferson University Hospital in Philadelphia (2009;112[1]: 95-103).
Study Reaffirms Low Risk for csPCa with Biopsy Omission After Negative Prostate MRI
December 19th 2024In a new study involving nearly 600 biopsy-naïve men, researchers found that only 4 percent of those with negative prostate MRI had clinically significant prostate cancer after three years of active monitoring.
Study Examines Impact of Deep Learning on Fast MRI Protocols for Knee Pain
December 17th 2024Ten-minute and five-minute knee MRI exams with compressed sequences facilitated by deep learning offered nearly equivalent sensitivity and specificity as an 18-minute conventional MRI knee exam, according to research presented recently at the RSNA conference.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.
