The authors report their experience about 2,422 examinations with double contrast radiography in the study of the gastric posterior wall. This technique is of great value in the detection, analysis and follow-up of gastric ulcerations. In 54 per cent of cases, the double contrast radiography showed endoscopically proven ulcerations, which where not recognized by standard barium meal technique. The diagnosis of the benign tumours of the posterior wall of the stomach has been also increased bay double contrast radiography. Thus, this technique is recommended for routine examination of the stomach.

The CT findings of extranodal natural killer/T-cell lymphoma, nasal type involving the gastrointestinal tract.
Eur Radiol
January 2025
Department of Radiology, The Sixth Affiliated Hospital, Sun Yat-sen University, Guangzhou, China.
Objectives: To analyze the CT imaging features of extranodal natural killer/T (NK/T)-cell lymphoma, nasal type (ENKTCL-NT) involving the gastrointestinal tract (GI), and to compare them with those of Crohn's disease (CD) and diffuse large B-cell lymphoma (DLBCL).
Materials And Methods: Data were retrospectively collected from 17 patients diagnosed with GI ENKTCL-NT, 68 patients with CD, and 47 patients with DLBCL. The CT findings of ENKTCL-NT were analyzed and compared with those of CD and DLBCL.
Impact of tissue-independent positron range correction on [Ga]Ga-DOTATOC and [Ga]Ga-PSMA PET image reconstructions: a patient data study.
Eur J Nucl Med Mol Imaging
January 2025
Department of Radiology and Nuclear Medicine, Maastricht University Medical Center, Maastricht, The Netherlands.
Purpose: The positron range effect can impair PET image quality of Gallium-68 (Ga). A positron range correction (PRC) can be applied to reduce this effect. In this study, the effect of a tissue-independent PRC for Ga was investigated on patient data.

January 2025
Department of Ophthalmology & Visual Sciences, University of Adelaide, North Terrace, Adelaide, SA, 5000, Australia.
Purpose: To report the normative dimensions of the frontal nerve (FN) on fat-suppressed suppressed gadolinium (fs-gad) enhanced magnetic resonance imaging (MRI).
Method: A retrospective cohort study of patients who underwent coronal fs-gad T1-weighted MRI. Orbits were excluded if there was unilateral or bilateral pathology of the FN or optic nerve sheath (ONS), incomplete MRI sequences, poor image quality or indiscernible FN on radiological assessment.

Rhode Island Hospital, Warren Alpert Medical School of Brown University, Providence RI.
Coronary artery disease (CAD) remains a leading cause of morbidity and mortality worldwide, necessitating advancements in diagnostic techniques. Coronary CT angiography (CCTA) has emerged as a pivotal non-invasive tool for evaluating coronary artery anatomy and detecting atherosclerotic plaque burden with high spatial resolution. This review explores the evolution of CCTA, highlighting its technological advancements, clinical applications, and challenges.
