What Method Is Best for Detecting Prostate Cancer Metastases?
The imaging process provides the most time-efficient sequence with the highest lesion detection rate and conspicuity.
Gadolinium-enhanced T1-weighted volumetric interpolated breath-hold exam (VIBE) is best for detecting prostate cancer metastases, according to a study published in the American Journal of Roentgenology.
Researchers from Canada performed a prospective study to compare the diagnostic value of various MRI sequences used for whole-body (WB) 18F-fluorocholine (FCH) PET/MRI staging of patients with high-risk prostate cancer. The study included 58 patients with untreated high-risk prostate cancer. Ten patients underwent integrated WB FCH PET/MRI; 48 underwent FCH PET/CT and WB MRI. The researchers recorded metastatic sites and used histopathologic findings or clinical and imaging follow-up (or both) for standard of reference.
The results showed the gadolinium-enhanced T1-weighted volumetric interpolated breath-hold exam (VIBE) was the best of the four sequences:
Conspicuity of metastases on gadolinium-enhanced T1-weighted VIBE and WB DWI sequences was higher than that on Dixon T1-weighted sequences.
The researchers concluded that metastases from prostate cancer are best detected at DWI or gadolinium-enhanced T1-weighted VIBE sequences. The most time-efficient sequence with the highest lesion detection rate and conspicuity is gadolinium-enhanced T1-weighted VIBE.
Can MRI Have an Impact with Fertility-Sparing Treatments for Endometrial and Cervical Cancers?
January 9th 2025In a literature review that includes insights from recently issued guidelines from multiple European medical societies, researchers discuss the role of magnetic resonance imaging (MRI) in facilitating appropriate patient selection for fertility-sparing treatments to address early-stage endometrial and cervical cancer.
Surveillance Breast MRI Associated with Lower Risks of Advanced Second Breast Cancers
January 8th 2025After propensity score matching in a study of over 3,000 women with a personal history of breast cancer, researchers found that surveillance breast MRI facilitated a 59 percent lower risk in advanced presentations of second breast cancers.
Abbreviated MRI for Hepatocellular Carcinoma: What a New Meta-Analysis Reveals
January 6th 2025For hepatocellular carcinoma screening, a 19-study meta-analysis found the abbreviated MRI sequencing protocol of T2-weighted MRI, diffusion-weighted imaging (DWI) and hepatobiliary phase (HBP) imaging offered 88 percent sensitivity and 93 percent specificity.
New CT and MRI Research Shows Link Between LR-M Lesions and Rapid Progression of Early-Stage HCC
January 2nd 2025Seventy percent of LR-M hepatocellular carcinoma (HCC) cases were associated with rapid growth in comparison to 12.5 percent of LR-4 HCCs and 28.5 percent of LR-4 HCCs, according to a new study.
