- Contrast-enhanced US of the Liver and Kidney: A Problem-solving Modality
Contrast-enhanced US (CEUS) has an important role as a supplement to CT or MRI in clinical practice. The main established utilizations are in the […]
- The added value of contrast-enhanced ultrasound in evaluation of indeterminate small solid renal masses and risk stratification of cystic renal lesions
CONCLUSION: In our cohort, CEUS had high specificity and PPV to diagnose RCC in sSRMs excluding lipid-rich AML. CEUS had significantly higher […]
- Use of CEUS LI-RADS for the Accurate Diagnosis of Nodules in Patients at Risk for Hepatocellular Carcinoma: A Validation Study
CONCLUSION: This study showed excellent specificity for the CEUS LI-RADS LR-5 category, allowing for confident imaging diagnosis of HCC, without […]

- Radiological tumor response and histopathological correlation of hepatocellular carcinoma treated with stereotactic body radiation therapy as a bridge to liver transplantation
CONCLUSION: RECIST 1.1 radiologic response criteria may underestimate the response to treatment with SBRT, and radiologic estimation of percent tumor […]
- Convolutional neural networks versus radiologists in characterization of small hypoattenuating hepatic nodules on CT: a critical diagnostic challenge in staging of colorectal carcinoma
Our objective was to compare the diagnostic performance and diagnostic confidence of convolutional neural networks (CNN) to radiologists in […]
- Collateral Damage: The Impact of the COVID-19 Pandemic on Acute Abdominal Emergency Presentations
CONCLUSION: To date, there is little published data regarding the presentation and severity of illnesses during the coronavirus disease 2019 […]

- Imaging diagnosis and staging of pancreatic ductal adenocarcinoma: a comprehensive review
Pancreatic ductal adenocarcinoma (PDAC) has continued to have a poor prognosis for the last few decades in spite of recent advances in different […]
- Characterization of Indeterminate Liver Lesions on CT and MRI With Contrast-Enhanced Ultrasound: What Is the Evidence?
OBJECTIVE. CT or MRI is most commonly used for characterizing focal hepatic lesions. However, findings on CT and MRI are occasionally indeterminate. […]
- Diagnostic imaging of hepatocellular carcinoma at community hospitals and their tertiary referral center in the era of LI-RADS: a quality assessment study
CONCLUSIONS: Community hospital HCC diagnostic scans significantly lag in critical quality parameters of tumor enhancement, arterial phase timing, […]
- CT and MR imaging findings of the livers in adults with Fontan palliation: an observational study
CONCLUSION: The livers in post-Fontan adults show a unique morphology of blunt edge and lobulating surface with occasional nodularity. There is a […]
- Contrast-enhanced ultrasound approach to the diagnosis of focal liver lesions: the importance of washout
Contrast-enhanced ultrasound (CEUS) is a powerful technique for differentiating focal liver lesions (FLLs) without the risks of potential […]
