INTRODUCTION: Chondrosarcoma has the highest prevalence among the primary malignant bone tumors in adults over the age of 50, and the scapular region is the most affected anatomical site. CASE REPORT: We report the case of a 66-year-old female patient, with no previous medical history, who consulted for aggravating mixed, non-specific, and atraumatic pain in the right shoulder, evolving for a year. The radiological assessment, including a computed tomography (CT) scan, a magnetic resonance imaging, and a tumor CT-guided biopsy, confirmed the diagnosis of a Grade 2 chondrosarcoma...

What was the educational challenge?The complexity and variability of cross-sectional imaging present a significant challenge in imparting knowledge of radiologic anatomy to medical students.What was the solution?Recent advancements in three-dimensional (3D) segmentation and augmented reality (AR) technology provide a promising solution. These advances allow for the creation of interactive, patient-specific 3D/AR models which incorporate multiple imaging modalities including MRI, CT, and 3D rotational angiography can help trainees understand cross-sectional imaging...

INTRODUCTION: Whole body magnetic resonance imaging (WB-MRI) is a promising emerging imaging technology for detecting bone and soft tissue pathology, especially in the onco-hematological field. This study aims to evaluate cancer patients' experience of WB-MRI performed on a 3T scanner compared to other diagnostic total body examinations. MATERIAL AND METHOD: In this prospective committee-approved study, patients completed a questionnaire in person (n = 134) after undergoing a WB-MRI scan to collect data on their physical and psychological reactions during the scan, the global satisfaction level, and preference for other types of MRI or computed tomography (CT), or positron emission tomography (PET/CT)...

Adrenocortical carcinoma (ACC) is a rare type of cancer that is associated with a high rate of recurrence and poor prognosis. The main diagnostic approaches to adrenocortical cancer include CT scan, MRI and the promising role of 18 F-FDG PET/CT. The main therapeutic approaches include radical surgery of local disease and recurrences, as well as adjuvant mitotane therapy. The evaluation of adrenocortical carcinoma (ACC) could be difficult by using 18 F-FDG PET/CT in view of the significant association between the 18 F-FDG uptake and ACC...

BACKGROUND: Acute or chronic wrist pain is a common presentation to a general orthopedic surgeon. The wrist joint is considered one of the most complex articulations in the human body. The complex arrangement of the wrist's intrinsic and extrinsic ligaments and their biomechanics are challenging for the surgeon to diagnose the wrist pathology despite clinical examination. Radiographs, CT scans and MRI are a few modalities that diagnose wrist pathologies efficiently. The accuracy, sensitivity, and specificity in evaluating the chondral, bone, and ligamentous lesion are its limitations...

Periampullary diverticula are outpouches in the mucosa in the duodenum surrounding the ampulla of Vater. Most cases of periampullary diverticuli are asymptomatic, but complications can arise, increasing a patient's mortality. Diagnosis of periampullary diverticuli is often incidental during endoscopy or imaging studies for abdominal pain. When a patient with periampullary diverticuli is symptomatic, imaging modalities such as CT scan and MRI can help make the diagnosis, but a side-viewing endoscope provides direct visualization of the diverticuli and also allows for the potential treatment of the disease...

OBJECTIVE: The oblique sagittal orientation of the cervical neural foramina hinders the evaluation of cervical neural foraminal stenosis (CNFS) on traditional axial and sagittal slices. Traditional image reconstruction techniques to generate oblique slices only provide a view of foramina unilaterally. Here we present a simple technique for generating splayed slices that depict the bilateral neuroforamina simultaneously and assess its reliability compared to traditional axial windows. METHODS: Cervical computed tomography (CT) scans from 100 patients were retrospectively collected and de-identified...

Computed tomography (CT) is considered the gold standard for femoral version measurement. However, recent data have shown magnetic resonance imaging (MRI) as another modality to measure femoral version. This study aimed to correlate MRI and CT femoral version measurements in patients presenting with a femoroacetabular impingement (FAI)-related complaint. Patients (18-35 years old) who presented to the hip preservation clinic and radiology department with a suspected FAI diagnosis from 26 December 2018 to 4 March 2020 were included...

BACKGROUND: Cavernomas of the third ventricle are rare entities that provide significant therapeutic challenges. Because of the better view of the surgical field and the possibility to achieve a gross total resection (GTR), microsurgical approaches are more commonly used to target the third ventricle. Endoscopic transventricular approaches (ETVA), on the other hand, are minimally invasive procedures that can afford a straight corridor trough the lesion, avoiding bigger craniotomies. Moreover, these approaches have shown lower infectious risks and shorter hospitalization times...

Cancer is one of the vital diseases which lead to the uncontrollable growth of the cell, and it affects the body tissue. A type of cancer that affects the children below five years and adults in a rare case is called retinoblastoma. It affects the retina in the eye and the surrounding region of eye like the eyelid, and sometimes, it leads to vision loss if it is not diagnosed at the early stage. MRI and CT are widely used scanning procedures to identify the cancerous region in the eye. Current screening methods for cancer region identification needs the clinicians' support to spot the affected regions...

Advances in the scientific fields of photogrammetry and computer vision have led to the development of automated multi-image methods that solve the problem of 3D reconstruction. Simultaneously, 3D scanners have become a common source of data acquisition for 3D modeling of real objects/scenes/human bodies. This article presents a comprehensive overview of different 3D modeling technologies that may be used to generate 3D reconstructions of outer or inner surfaces of different kinds of targets. In this context, it covers the topics of 3D modeling using images via different methods, it provides a detailed classification of 3D scanners by additionally presenting the basic operating principles of each type of scanner, and it discusses the problem of generating 3D models from scans...
