Academic Future of Interventional Radiology Subspecialty: Are We Giving Enough Space to Radiology Trainees?

Background: The aim of this study was to investigate willingness and barriers to academic activities of radiology trainees interested in interventional radiology subspecialty.

Materials And Methods: Radiology trainees and fellows were called to participate a 35-question survey via online platforms and radiological societies. The research survey investigated on involvement in academic activities, willingness of a future academic career, and challenges for pursuing an academic career.

Alzheimer's disease: diagnosis by different methods of voxel-based morphometry.

Purpose: The purpose of this study was to determine the optimal computational options in voxel-based morphometry (VBM) for discrimination between Alzheimer's disease (AD) patients and healthy control (HC) subjects.

Materials And Methods: Structural magnetic resonance images of 24 AD patients and 26 HC subjects were analyzed using VBM to determine brain regions with significant gray matter (GM) loss due to AD. The VBM analyses were performed with 4 different computational options: gray matter concentration (GMC) analysis with and without global normalization, and gray matter volume (GMV) analysis, with and without global normalization.

Simultaneous arterial spin labeling cerebral blood flow and morphological assessments for detection of Alzheimer's disease.

Rationale And Objectives: The relative roles of arterial spin-labeling (ASL) perfusion imaging and magnetic resonance morphological assessment in diagnosing Alzheimer's disease (AD) have not been established. Our purposes were to directly compare the diagnostic performance of ASL regional cerebral blood flow (rCBF) measurement and that of morphological assessment, and to determine whether or not the combination of the two methods improves diagnostic performance.

Materials And Methods: We analyzed 23 consecutive, retrospectively identified AD patients and 23 healthy control subjects.

Contributing factors in the pathogenesis of acquired cholesteatoma: size analysis based on MDCT.

Objective: The purpose of this article is to explore the factors that contribute to the occurrence of cholesteatoma. We studied the size of the mastoid air cells and the tympanic cavity using high-resolution CT.

Materials And Methods: Temporal bone CT scans of consecutive patients with unilateral cholesteatoma and healthy control subjects were retrospectively analyzed.

Sensorineural hearing loss: there is no correlation with isolated dysplasia of the lateral semi-circular canal on temporal bone CT.

Background: Inner ear malformations may cause sensorineural hearing loss (SNHL). However, the correlation between the small lateral semi-circular canal (LSCC) and SNHL is controversial.

Purpose: To determine whether there is a correlation between the two using CT-based measurement.

Morphologic change in vertebral body after percutaneous vertebroplasty: follow-up with MDCT.

Objective: The purpose of this prospective study was to evaluate maintenance of spinal canal size and restoration of vertebral height and wedge angle after percutaneous vertebroplasty.

Subjects And Methods: This study included 27 patients (19 women, eight men) with osteoporotic compression fractures (52 vertebrae). MDCT with multiplanar reformation was performed within 1 day before and 1 hour after the procedure and 1 year after the procedure on a routine or as-needed basis.

Asymmetrical cerebral perfusion demonstrated by noninvasive arterial spin-labeling perfusion imaging in a patient with corticobasal degeneration.

This is to report arterial spin-labeling (ASL) regional cerebral blood flow (rCBF) mapping findings in a case of corticobasal degeneration (CBD). A 68-year-old man gradually developed limb-kinetic apraxia, myoclonus, and rigidity in the left hand and was diagnosed as having CBD. Magnetic resonance imaging and single photon emission computed tomography revealed atrophy and decreased blood flow, respectively, in the right hemisphere, findings that were compatible with CBD.
