Article Synopsis
- This study aimed to evaluate the added value of hepatobiliary phase (HBP) contrast agents in diagnosing hepatocellular carcinoma (HCC) by reviewing existing meta-analyses since 2010.
- Data from 13 studies, which included a total of 1184 HCC lesions, were analyzed to compare diagnostic performance metrics (sensitivity and specificity) between methods using HBP and those without it.
- Results showed that while both methods were effective, there was no statistically significant difference in sensitivity between the two approaches, indicating that HBP may not enhance HCC diagnosis as previously thought.
Features of shell and genitalia as well as nucleotide sequences of selected mitochondrial and nuclear genes of specimens of from ten northern French and two Dutch populations were compared with the same features of British and Italian populations. They were found to be very similar to populations previously identified as belonging to the CAN-1 lineage of . This confirms previous suggestions that was introduced to western Europe (England, France and the Netherlands) in historical times.

- The study looked at how to tell the difference between benign (non-cancerous) and malignant (cancerous) liver lesions using a special MRI with a substance called gadoxetic acid.
- Researchers examined 107 patients with 180 liver lesions, analyzing both benign and malignant types.
- They discovered that there were significant differences in the measurements taken from these lesions, which could help doctors determine if a lesion is cancerous or not.
Article Synopsis
- The study evaluated the effectiveness of core biopsy for diagnosing pancreatic cancer, focusing on its sensitivity, accuracy, and safety.
- In a group of 100 patients, core biopsy showed a sensitivity of 92%, specificity of 100%, and an accuracy of 93.3%, with only 1% experiencing serious complications.
- The findings suggest that core biopsy may be more effective and cost-efficient than the commonly used endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) for obtaining tissue samples.
Cardiac Magnetic Resonance Relaxometry Parameters, Late Gadolinium Enhancement, and Feature-Tracking Myocardial Longitudinal Strain in Patients Recovered from COVID-19.
J Cardiovasc Dev Dis
June 2023
COVID-19 infection is associated with myocarditis, and cardiovascular magnetic resonance (CMR) is the reference non-invasive imaging modality for myocardial tissue characterization. Quantitative CMR techniques, such as feature tracking (FT) and left ventricular global longitudinal strain (GLS) analysis, have been introduced as promising diagnostic tools to improve the diagnostic accuracy of suspected myocarditis. The aim of this study was to analyze the left ventricular global longitudinal strain (GLS) and the influence of T1 and T2 relaxation times, ECV, and LGE appearance on GLS parameters in a multiparametric imaging protocol in patients who recovered from COVID-19.
