Improved diagnostic performance of plain radiography for cervical ossification of the posterior longitudinal ligament using deep learning.

Background: A high false-negative rate has been reported for the diagnosis of ossification of the posterior longitudinal ligament (OPLL) using plain radiography. We investigated whether deep learning (DL) can improve the diagnostic performance of radiologists for cervical OPLL using plain radiographs.

Materials And Methods: The training set consisted of 915 radiographs from 207 patients diagnosed with OPLL.

Imaging findings of pneumonia: emphasis on CT findings between immunocompromised and immunocompetent patients.

Background: () is a globally emerging, rare, waterborne, aerobic, gram-negative, multiple-drug-resistant organism, most commonly associated with respiratory tract infection in humans. Computed tomography (CT) findings in patients with pneumonia are rarely reported.

Purpose: To compare CT findings between immunocompromised and immunocompetent patients, and to determine characteristic imaging findings of pneumonia.

Fat quantification of multifidus muscle using T2-weighted Dixon: which measurement methods are best suited for revealing the relationship between fat infiltration and herniated nucleus pulposus.

Objective: To reveal the best-suited method for fat quantification of lumbar multifidus to demonstrate its relationship to herniated nucleus pulposus (HNP) using T2-weighted Dixon.

Materials And Methods: One hundred eight patients who underwent MRI for low back pain were enrolled. Two readers independently analyzed the fat fraction (Ff) using axial two-dimensional (D), coronal 2-D, and coronal 3-D measurement.

Imaging findings of complications after thoracic surgery.

Many surgical procedures are used for the treatment of lung, heart, and mediastinal diseases. The techniques can result in postoperative complications. The nature of these complications differs according to the duration of thoracic surgery and the onset of the complication.

Ultrasonography of the pediatric hip and spine.

Ultrasonography (US) is a useful screening method for the diagnosis of developmental dysplasia of the hip (DDH) and congenital spinal anomalies in infants. In addition, US is a useful, noninvasive imaging modality for the diagnosis of transient synovitis in children. The early detection of DDH leads to a better prognosis without surgical intervention.
