Solid tumours showing oligoprogression to immune checkpoint inhibitors have the potential for abscopal effects
ConclusionPatients with oligoprogressive disease may be promising targets with potential for AEs. AEs can lead to improved PFS and, in rare cases, to a certain progression-free period without treatment.Secondary AbstractIrradiating solid tumours in patients with oligoprogressive disease during immune checkpoint inhibitor therapy may be a promising target with the potential for abscopal effects (AEs). AEs can lead to improved progression-free survival and, in rare cases, to a certain progression-free period without treatment. (Source: Japanese Journal of Radiology)

Improvement of motion artifacts using dynamic whole-body 18F-FDG PET/CT imaging
ConclusionSerial dynamic whole-body FDG PET imaging can minimize body motion artifacts by summation of the images before the body motion. Such serial dynamic study may be a choice for PET imaging to eliminate motion artifacts. (Source: Japanese Journal of Radiology)

Quantitative susceptibility mapping shows lower brain iron content in children with childhood epilepsy with centrotemporal spikes
ConclusionsThis study suggests that the potential iron deficiency in certain brain regions is associated with CECTS, which might be helpful for further illumination of potential pathogenesis mechanism of CECTS. (Source: Japanese Journal of Radiology)

Comparison between InterDosi and MCNP in the estimation of photon SAFs on a series of ICRP pediatric voxelized phantoms
AbstractIn the present work, a new Monte Carlo Geant4 based code called InterDosi 1.0, was used to simulate specific absorbed fractions (SAFs) in the six reference pediatric voxel-based phantoms developed by the International Commission on Radiological Protection (ICRP). The aim of this study was to assess the ability of this code to estimate SAFs in a variety of voxel-based phantoms. A large number of photon SAFs were calculated for pairs of organs corresponding to three sources and 170 target organs/regions. A total of 108 initial photons were uniformly emitted from the source organs with eight discrete energies. In orde...

Extra-articular location of the three-dimensional mechanical axis in advanced knee osteoarthritis: an upright computed tomography study
ConclusionOur analysis demonstrated that the 3D-MA in low-grade OA knees passes slightly medial and posterior to the knee center, and the 3D-MA is translated medioposteriorly with the progression of knee OA. Further, the 3D-MA is translated medially with varus progression and posteriorly with the progression of knee flexion contracture. (Source: Japanese Journal of Radiology)

Percutaneous computed tomography-guided core needle biopsy can be used to histologically confirm the clinical features and long-term prognosis of pulmonary neuroendocrine neoplasms
ConclusionPNENs may be pathologically diagnosed using PCT-CNB. While differential diagnoses between LCNEC and SCLC are problematic in some patients, a HGNEC-NOS diagnosis was ascribed and PCT-CNB samples were shown to predict NEN OS rates. (Source: Japanese Journal of Radiology)

Radiation therapy of cancer in the adolescent and young adult (AYA) generation
AbstractCancer of the adolescent and young adult (AYA) generation has received increasing attention in recent years, however, there were few reports on radiotherapy for this area. As for pediatric cancer, many cancer of the AYA generation were treated with radiation therapy as the multidisciplinary treatment. In this article, we will review reproductive complications, which are considered to be particularly important complications of radiation therapy for AYA generation, and describe investigation of radiation therapy for cancers of the AYA generations at the Hyogo Cancer Center and the Hyogo Ion Beam Medical Center Kobe P...

Performance of artificial intelligence-based software for the automatic detection of lung lesions on chest radiographs of patients with suspected lung cancer
ConclusionThe nodule detection sensitivity of CXR-AID on chest radiographs was 0.80, and the non-target and non-target normal areas per image were 0.85 and 0.24, respectively. Larger, solid nodules without overlapping structures were detected more readily by CXR-AID. (Source: Japanese Journal of Radiology)
