Objective: Doppler findings in women with severe symptoms of primary dysmenorrhea include high impedance to blood flow in uterine arteries with a preserved cyclic pattern throughout the whole cycle. Doppler findings in women who present with mild symptoms of primary dysmenorrhea are not yet documented. The aim of this study was to investigate possible differences in Doppler findings among women with mild and severe primary dysmenorrhea.
Study Design: One hundred and fifty four women were examined with color Doppler ultrasound: 50 in the control group, 60 in the mild and 44 in the severe primary dysmenorrhea subgroup. We calculated resistance index in uterine arteries in these women on the first day of the cycle, in the follicular (days 9-12) and the luteal (days 20-23) phase of the cycle and used analysis of variance for comparing results.
Results: The rate of visualization was 100% for uterine and arcuate arteries, 44-76% for the radial and 32-62% for spiral arteries, respectively. A significant difference in Doppler index values among the mild and severe dysmenorrheic group was observed in the luteal phase for the arcuate artery and in all the three measurement periods for the radial and spiral arteries.
Conclusion: There is a difference in Doppler findings between women with mild and severe symptoms of primary dysmenorrhea.

Magnetic resonance imaging (MRI) is frequently used to monitor disease progression in multiple sclerosis (MS). This study aims to systematically evaluate the correlation between MRI measures and histopathological changes, including demyelination, axonal loss, and gliosis, in the central nervous system of MS patients. We systematically reviewed post-mortem histological studies evaluating myelin density, axonal loss, and gliosis using quantitative imaging in MS.

Purpose: The study explores the role of multimodal imaging techniques, such as [F]F-PSMA-1007 PET/CT and multiparametric MRI (mpMRI), in predicting the ISUP (International Society of Urological Pathology) grading of prostate cancer. The goal is to enhance diagnostic accuracy and improve clinical decision-making by integrating these advanced imaging modalities with clinical variables. In particular, the study investigates the application of few-shot learning to address the challenge of limited data in prostate cancer imaging, which is often a common issue in medical research.

Background: Irritable bowel syndrome (IBS) has been effectively treated with acupuncture, but the significance of quality of life, depression, and anxiety in the assessment of IBS patients has received little consideration. This study examined the impact of acupuncture on depression, anxiety, and quality of life in IBS patients.
Method: PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI), EMBASE, China Science and Technology Journal Database (VIP), Chinese Biological Medical (CBM, SinoMed) Database, and the Wan Fang Database were among the electronic databases from which relevant randomized controlled trials (RCTs) were systematically retrieved between their inception and July 2023.
Determination of adequate bony resection margins in inflammatory jaw pathologies using SPECT-CT in primary mandibular reconstruction with virtually planned vascularized bone flaps.

Objectives: In advanced stages of osteoradionecrosis, medication-related osteonecrosis of the jaw, and osteomyelitis, a resection of sections of the mandible may be unavoidable. The determination of adequate bony resection margins is a fundamental problem because bony resection margins cannot be secured intraoperatively. Single-photon emission computed tomography (SPECT-CT) is more accurate than conventional imaging techniques in detecting inflammatory jaw pathologies.
