Background: Magnetic resonance (MR)-guided high-intensity focused ultrasound (HIFU) can palliate metastatic bone pain by periosteal neurolysis. We investigated the value of diffusion-weighted imaging (DWI) for monitoring soft tissue changes adjacent to bone during MR-guided HIFU. We evaluated the repeatability of the apparent diffusion coefficient (ADC) measurement, the temporal evolution of ADC change after sonication, and its relationship with thermal parameters. Methods: Ex-vivo experiments in lamb legs ( n = 8) were performed on a Sonalleve MR-guided HIFU system...

AIM: To investigate whether endoscopic ultrasound (EUS)-guided insertion of fully covered self-expandable metal stents in walled-off pancreatic necrosis (WOPN) is feasible without fluoroscopy. METHODS: Patients with symptomatic pancreatic WOPN undergoing EUS-guided transmural drainage using self-expandable and fully covered self expanding metal stents (FCSEMS) were included. The EUS visibility of each step involved in the transmural stent insertion was assessed by the operators as "visible" or "not visible": (1) Access to the cyst by needle or cystotome; (2) insertion of a guide wire; (3) introducing of the diathermy and delivery system; (4) opening of the distal flange; and (5) slow withdrawal of the delivery system until contact of distal flange to cavity wall...

BACKGROUND: Hemodialysis requires needle insertions every treatment. Needle injury (mechanical or hemodynamic) may cause complications (aneurysms/stenosis) that compromise dialysis delivery requiring interventions. Metal needles have a sharp slanted "V"-shaped cutting tip; plastic cannulae have a dull round tip and four side holes. Preliminary observations demonstrated a difference in intradialytic blood flow images and mean Doppler velocities at cannulation sites between the two devices...

We report the case of an 88-year-old female with obstructive jaundice due to a periampullary tumor. The patient developed acute cholangitis and consequent clinical deterioration, so it was decided to perform palliative biliary drainage. Due to duodenal tumor invasion, it was not possible to perform endoscopic retrograde cholangiopancreatography. A different approach was attempted and it was decided to carry out an endoscopic ultrasound-guided choledochoduodenostomy. This procedure was performed with a linear echoendoscope, and using a duodenal bulbar approach, a fistula was created between the bulb and the common bile duct...

PURPOSE: The use of ultrasound imaging is not widespread in prostate cancer radiotherapy workflows, despite several advantages (e.g. allowing real-time volumetric organ tracking). This can be partially attributed to the need for a trained operator during acquisition and interpretation of the images. We introduce and evaluate an algorithm that can propose a patient-specific transperineal ultrasound probe setup, based on a CT scan and anatomical structure delineations. The use of this setup during the simulation and treatment stage could improve usability of ultrasound imaging for relatively untrained operators (radiotherapists with less than one year experience with ultrasound)...
