Novel Fusion Imaging of Muscle, Plaque, Arteries, and Bone Using MR Imaging for Carotid Endarterectomy Patients.

Department of Neurosurgery, Ken-o-Tokorozawa Hospital, Tokorozawa, Saitama, Japan.
Background: Indications for carotid endarterectomy (CEA) and reduction of complications require evaluation of the plaque properties and location of the distal end of the plaque. High cervical location can be predicted from the anatomy of the vertebral body and mandibular bones, and the locations of the posterior belly of the digastric muscle and stylohyoid muscle. Magnetic resonance (MR) imaging without contrast medium is useful for preoperative evaluation of the plaque, arteries, and bone characterization.

Introduction: Distal arterial occlusions can cause measurable changes in the flow wave profile in proximal segments of the feeding artery. Our objective was to study the diagnostic accuracy of point-of-care ultrasound (POCUS) of the common carotid arteries (CCA) for detection of anterior circulation large vessel occlusion (ac-LVO) in patients with suspected stroke.
Patients And Methods: We conducted a prospective, single-center, observational study of adult patients with suspected stroke admitted in the emergency department.

Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory vascular disease of medium-sized arteries that causes abnormal cellular growth in arterial walls and most commonly affects young to middle-aged women (20-50 years of age). While FMD often involves the renal arteries, it can affect any arterial bed. FMD has a characteristic angiographic appearance of a "string of beads.

Objective: To explore the anatomical and clinical factors that affect the radiographic exposure time in radial artery cerebral angiography and to establish a model.
Method: A total of 210 patients who underwent radial artery cerebral angiography at this center from September 2021 to May 2022 were selected, and their anatomical and clinical factors were analyzed to evaluate the correlation between these factors and the duration of radiographic exposure. A related neural network prediction model was established.
Short common trunk of the occipital artery and ascending pharyngeal artery arising from the internal carotid artery diagnosed by magnetic resonance angiography.

Department of Neurosurgery, Saitama Sekishinkai Hospital, 2-37-20 Irumagawa, Sayama, Saitama, 350-1305, Japan.
Purpose: To describe a case of short common trunk of the occipital artery (OA) and ascending pharyngeal artery (APA) arising from the internal carotid artery (ICA).
Methods: A 36-year-old woman with a history of surgical resection of a right lateral ventricular meningioma and atheromatous plaque of the right ICA underwent cranial magnetic resonance (MR) imaging and MR angiography of the head and neck region with a 3-Tesla scanner.
Results: MR angiography of the neck region showed a small atheromatous plaque at the origin of the right ICA and an anomalous artery arising from the posteromedial aspect of the right ICA at the distal end of the carotid bulb.
