Focused ultrasound (FUS)-mediated blood-brain barrier disruption (BBBD) can enable even large therapeutics such as stem cells to enter the brain from the bloodstream. However, the efficiency is relatively low. Our previous study showed that human neural progenitor cells (hNPCs) loaded with superparamagnetic iron oxide nanoparticles (SPIONs) in culture were attracted by an external magnetic field. In vivo, enhanced brain retention was observed near a magnet mounted on the skull in a rat model of traumatic brain injury, where BBBD also occurs...

Calcific tendinopathy of the rotator cuff is a common cause of shoulder pain. Inflammation of the rotator cuff tendons may be complicated by adjacent bone erosion and subsequent migration of calcific deposits within the bone resulting in marrow inflammation. Bone marrow involvement is not readily visible using X-ray and ultrasound (US) and further testing is necessary. Magnetic resonance imaging (MRI) is a highly sensitive technique that can detect a focal bone T1 and T2-weighted hypointensity with bone marrow edema-like signal and cortical erosion...

Uncommon liver lesions pose a diagnostic challenge because of unfamiliar imaging findings. For simplification, these lesions can be divided into four broad categories based on the dominant imaging feature in each: hypervascular, hypovascular, fat-containing, or cystic lesions. In this review, we profile the radiological features of uncommon liver lesions on multimodality imaging including ultrasound (US), computed tomography (CT), magnetic resonance imaging (MRI), and nuclear medicine.

Gallbladder (GB) adenomyomatosis (ADM) is a benign, acquired anomaly, characterized by hypertrophy of the mucosal epithelium that invaginates into the interstices of a thickened muscularis forming so-called Rokitansky-Aschoff sinuses. There are three forms of ADM: segmental, fundal and more rarely, diffuse. Etiology and pathogenesis are not well understood but chronic inflammation of the GB is a necessary precursor. Prevalence of ADM in cholecystectomy specimens is estimated between 1% and 9% with a balanced sex ratio; the incidence increases after the age of 50...

Contrast-enhanced ultrasound (CEUS) is a specialized form of ultrasound (US) performed with an intravenous injection of microbubble contrast agents. It has been successfully used for a variety of applications including characterization of liver tumors. In April 2014, the American College of Radiology (ACR) convened a working group of international experts to develop ACR CEUS Liver Imaging Reporting and Data System (CEUS LI-RADS). An initial version of CEUS LI-RADS was published in August 2016. Although the CEUS LI-RADS concept and principles for liver lesion characterization, using dynamic contrast enhancement features, are similar to those for CT or MRI, there are significant differences between CT/MRI and CEUS LI-RADS...
