Chest wall lesions comprise benign and malignant etiologies. Numerous classification systems have been proposed based on etiology, origin site, tissue composition and whether the lesion is benign or malignant. Despite that conventional radiological studies are able to provide detailed information about the tumor morphology such as size, location, and extent tissue characteristics, yet, they cannot

Diffusion tensor imaging of brain changes in patients with chronic kidney disease before cognitive impairment with 3 T MRI device Egypt. J. Radiol. Nucl. Med. Pub Date : 2024-01-03 Sherif Abdel Fattah Moustafa, Dina Abd Elnasser Rizk, Lamiaa Galal El Serougy, Mohamed El Said El Azab, Wessam Mustafa
Patients with chronic kidney disease (CKD) are at risk of a many of central nervous system complications such as stroke and cognitive impairment. Studies based on diffusion tensor imaging (DTI) confirmed that the integrity of white matter in CKD patients has changed and these alterations can be observed before tissue morphological changes occurring on conventional MRI. Early use of DTI in CKD patients

Testicular leukaemic infiltration in relapsed acute lymphoblastic leukaemia: a case report Egypt. J. Radiol. Nucl. Med. Pub Date : 2024-01-02 Abdul Qadir Qader, Javid Akhgar, Stephanie Wai Yee Tan, Hamzaini Abdul Hamid
Although paediatric patients with acute lymphoblastic leukaemia (ALL) have improved survival following modern chemotherapy treatment, disease relapses still occur in 20–25% of them. Our case had relapsed ALL with testicular leukaemic infiltration, which is rare, with less than 2% incidence. We describe a case of an 11-year-old boy with a background history of ALL presenting with painless unilateral

Evaluating the index of panoramic X-ray image quality using K-means clustering method Egypt. J. Radiol. Nucl. Med. Pub Date : 2024-01-02 Satoshi Imajo, Yoshinori Tanabe, Nobue Nakamura, Mitsugi Honda, Masahiro Kuroda
A panoramic X-ray image is generally considered optimal when the occlusal plane is slightly arched, presenting with a gentle curve. However, the ideal angle of the occlusal plane has not been determined. This study provides a simple evaluation index for panoramic X-ray image quality, built using various image and cluster analyzes, which can be used as a training tool for radiological technologists

Interrater reliability of the ovarian–adnexal reporting and data system magnetic resonance imaging (O‑RADS MRI) Egypt. J. Radiol. Nucl. Med. Pub Date : 2024-01-02 Zainab A Ramadan, Ahmed Abdel Khalek Abdelrazek, Fatmaelzahraa Abdelfattah Denewar
The current study aims to evaluate interrater reliability of ovarian–adnexal reporting and data system (O-RADS) magnetic resonance imaging (MRI) in interpretation of adnexal and ovarian lesions. Retrospective analysis of 131 ovarian lesions was as done for 106 consecutive female patients with adnexal and/or ovarian lesions that underwent MR imaging of the pelvis. Images interpretation was accomplished

Closed bowel loop obstruction by a fibrous band mimicking paraduodenal hernia Egypt. J. Radiol. Nucl. Med. Pub Date : 2024-01-02 Marco Tadrous, Ahmed Abdelmonem Darweesh
A closed-loop obstruction occurs when a section of the intestine becomes blocked at two locations along its pathway, increasing the likelihood of volvulus and ischemia. Frequently, a single adhesive band is the primary cause of a closed loop, although internal hernias from congenital defects or iatrogenic intervention in the mesentery or omentum can also become other factors. In closed-loop obstruction

Preoperative visualization of mammary artery for breast reduction surgery based on computed tomography angiography Egypt. J. Radiol. Nucl. Med. Pub Date : 2024-01-02 Xiaoshi Li, Jigang Geng, Dayong Jin, Yinhu Zhu, Xin Li, Lei Wang, Yue Qin
Macromastia, characterized by an increase in breast size, poses challenges such as elevated body burden and chest oppression, potentially leading to cardiac and pulmonary overload. A crucial aspect of addressing these challenges involves preoperative planning, aiming to acquire detailed images and a 3D model of the internal mammary artery with minimal radiation exposure. This study aimed to explore

Variations in external carotid artery branches and common carotid bifurcation level: a computed tomography angiography study Egypt. J. Radiol. Nucl. Med. Pub Date : 2023-12-20 Tarek Fawzy Abd Ella, Mohammed Salah Eldeen El Zawawi, Ahmed Gaber Elsawaf, Mahmoud Mohamed Moawad
The common carotid bifurcation level is an important surgical landmark during head and neck surgery, especially endarterectomy, that could be omitted in patients with high bifurcation levels to reduce damage to neighboring structures like the hypoglossal nerve. Additionally, having a thorough understanding of the variations in the external carotid artery branches is crucial for head and neck cancer

MRI T2 mapping and quantitative ultrasound shear wave elastography in cartilage integrity assessment for juvenile idiopathic arthritis patients Egypt. J. Radiol. Nucl. Med. Pub Date : 2023-12-19 Wessam Abdelrahman Elzayat, Moustafa Hussein Abdelrahman, Hend Mohamed Abu Shady, Hadeel Mohamed Seif
Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease in childhood that can lead to irreversible cartilage damage, with associated disability and decreased life quality. Shear wave elastography and quantitative MRI mapping can be used to identify early cartilage affection. To evaluate diagnostic utility of distal femoral cartilage shear wave elastography and MRI T2 mapping

Head-to-head comparison of ultrasound and 99mTc-glucosamine SPECT/CT imaging of patients with rheumatoid arthritis: a single center prospective study Egypt. J. Radiol. Nucl. Med. Pub Date : 2023-12-15 Osayande Evbuomwan, Gerrit Engelbrecht, Cathryn Driver, Joseph Sempa, Barend Jansen van Rensburg, Mathys Labuschagne, Je’nine Horn-Lodewyk
Rheumatoid arthritis (RA) is an inflammatory disease that can lead to progressive joint damage. Early identification of synovitis is key in the management of patients with RA. The aim of this study was to assess synovitis in patients with RA using 99mTc-glucosamine single photon emission computed tomography/computed tomography (SPECT/CT) imaging and compare this radiopharmaceutical's diagnostic performance
