Microvascular Flow Imaging: A State-Of-The-Art Review Of Clinical Use And Promise., Muhammad Usman Aziz, John R Eisenbrey, Annamaria Deganello, Mohd Zahid, Kedar Sharbidre, Paul Sidhu, Michelle L Robbin

Department of Radiology Faculty Papers

Vascular imaging with color and power Doppler is a useful tool in the assessment of various disease processes. Assessment of blood flow, from infarction and ischemia to hyperemia, in organs, neoplasms, and vessels, is used in nearly every US investigation. Recent developments in this area are sensitive to small-vessel low velocity flow without use of intravenous contrast agents, known as microvascular flow imaging (MVFI). MVFI is more sensitive in detection of small vessels than color, power, and spectral Doppler, reducing the need for follow-up contrast-enhanced US (CEUS), CT, and MRI, except when arterial and venous wash-in and washout characteristics would …

Artificial Intelligence In Ultrasound Imaging: Current Research And Applications, Shuo Wang, Bs, Ji-Bin Liu, Md, Ziyin Zhu, Md, John Eisenbrey, Phd

Department of Radiology Faculty Papers

Artificial intelligence (AI) is an area of computer science that emphasizes the creation of intelligent software or system based on big data information, machine learning and deep learning technologies. The rapid development of science and technology as well as internet communication has enabled AI and big data to gradually apply to many fields of health care. The modern imaging medicine is one of the first areas that AI can play an important role and applications. As cross-sectional imaging, ultrasound (US) is well suitable for AI technology to standardize imaging protocols and improve diagnostic accuracy. This article reviews current AI technology …

Delayed Hepatic Rupture Post Ultrasound-Guided Percutaneous Liver Biopsy: A Case Report., Jia-Yan Huang, Qiang Lu, Ji-Bin Liu

Department of Radiology Faculty Papers

RATIONALE: Hemorrhage, one of complications after liver biopsy, is often identified immediately after the procedure while delayed liver rupture is relatively rare.

PATIENT CONCERNS: A 45-year-old woman was diagnosed with undetermined liver cirrhosis and abnormal liver function. To determine the etiology and severity of liver cirrhosis, ultrasound-guided liver biopsy was arranged. The patients did not complain any pain during the procedure. Ultrasound examination on postoperative day1 (POD 1) and MRI on POD 3 showed no evidence of hematoma and ascites. On POD 7, however, the patient was taken to the hospital with a sudden onset of pain in the right …

Simple Linear Measurements Of The Normal Liver: Interobserver Agreement And Correlation With Hepatic Volume On Mri, Sachit K. Verma, Kristen Mcclure, Laurence Parker, Donald G. Mitchell, Manisha Verma, Diane Bergin

Department of Radiology Faculty Papers

OBJECTIVE. To retrospectively evaluate interobserver agreement for 4 manually determined linear hepatic measurements on magnetic resonance imaging (MRI) and correlation of these linear measurements with hepatic volume.

MATERIALS AND METHODS. Hepatic linear measurements: midhepatic point craniocaudad (MHP CC), maximum CC to liver tip (Max CC), maximum transverse and MHP anteroposterior (AP) dimensions were performed on 116 patients without liver disease who had 1.5 T MR imaging of the abdomen.Linear measurements: MHP CC, Max CC, maximum transverse, MHP AP dimensions and products of CC with MHP AP dimension were correlated with hepatic volumes. Correlation analysis (Pearson product moment correlation), Student t …

Us And Mr Imaging Features Of Benign Cystic Mesothelioma Of The Liver: A Diagnostic Dilemma, Sachit K. Verma, Donald G. Mitchell, Oksana H. Baltarowich, Diane Bergin, Raphael Rubin

Department of Radiology Faculty Papers

Cystic mesotheliomas are benign neoplasms, often seen in the parietal and visceral peritoneum, omentum and pelvic organs, and are exceedingly rare in the liver. It is however important to be familiar with the radiological findings of this tumour because the signal-intensity and enhancement pattern of this tumor are unusual and not typical for any of the more frequently seen mass lesions. In our patient, characteristic imaging findings on dynamic contrast-enhanced MRI and histopathological confirmation with appropriate immunohistochemical markers facilitated a correct diagnosis. We herein describe the clinical, imaging and histopathological features, pathogenesis, differential diagnosis and treatment of benign cystic mesothelioma …
