The objective of this study was to test the hypothesis that bitemporal hemianopsia (BHA) is most common visual field (VF) defect in patients with pituitary macroadenoma and assess degree optic pathway compression necessary produce defects.We reviewed MRI findings medical records 119 who had undergone formal assessment VFs. We then evaluated displacement caused by macroadenoma, as observed on MR images. classifications included no contact, abutment but displacement, mild (< 3 mm), moderate (≥...

Hypoxic-ischemic injury (HII) continues to be an important cause of neonatal mortality and morbidity. In recent years, the role magnetic resonance (MR) imaging has increased by providing early detection initiate preventive measures assess severity tissue injury, it often serves as a prognostic indicator. However, because subtle findings temporal variability signal abnormalities, diagnosis remains troublesome, particularly for trainees general radiologists who do not encounter these findings....

Abstract Purpose: There are no effective medical therapies for patients with meningioma who progress beyond surgical and radiotherapeutic interventions. Somatostatin receptor type 2 (SSTR2) represents a promising treatment target in meningiomas. In this multicenter, single-arm phase II clinical study (NCT03971461), the SSTR2-targeting radiopharmaceutical 177Lu-DOTATATE is evaluated its feasibility, safety, therapeutic efficacy these patients. Patients Methods: Adult progressive intracranial...

Objective To determine imaging features that may separate adamantinomatous and papillary variants of craniopharyngiomas given tumors with signature are associated higher recurrence rates, morbidity, mortality. We specifically reviewed calcification on CT, T1 bright signal intensity, cystic change T2 weighted images for differentiating these two types. Methods retrospectively the MRI CT studies in 38 consecutive patients pathologically proven between January 2004 February 2014 presence scans,...

Radiolabeled somatostatin receptor (SSTR) agonists 68Ga-DOTA-TATE and 68Ga-DOTA-TOC are widely applied for imaging of patients with neuroendocrine tumors (NETs). Preclinical preliminary clinical evidence has indicated that SSTR antagonists perform better NET imaging. In this study, we assessed the feasibility using a new hybrid chelator DATA5m ((6-pentanoic acid)-6-(amino)methyl-1,4-diazepinetriacetate))-conjugated kit-type antagonist 68Ga-DATA5m-LM4 PET evaluated safety, biodistribution,...

Implantation of a spinal cord stimulator (SCS) is one option for pain control in individuals with chronic lumbosacral radicular or axial lumbar pain. The expected positioning SCSs based on the location pain, types electrodes (percutaneous vs surgical paddle), and electrode arrays potential complications have not been described to date radiology literature.A 5-year retrospective review information system at our institution revealed 24 patients images 36 SCSs. Those were reviewed identify type...

<h3>SUMMARY:</h3> Middle ear adenomas are rare benign tumors, which can easily be mistaken for other conditions radiologically. They derive from the middle mucosa. We report case of a 48-year-old man with history decreased left-sided hearing and intermittent pulsatile tinnitus. High-resolution CT temporal bones revealed well-defined left soft-tissue attenuation abutting head malleus. Surgical excision adenoma.

Ankle dislocations are orthopedic emergencies that require immediate treatment to avoid neurovascular impairment. They usually accompanied by one or more comminuted fractures of the ankle mortis. In rare circumstances, such as high‐energy trauma, may not be concomitant malleolar and, thus, named “pure dislocations”. We presented a very and interesting case an open medial dislocation without associated fracture in 18‐year‐old man with no known predisposing risk factors. The patient was...
