MRI Is Better Than CT Scan for Detection of Structural Pathologies After Traumatic Posterior Hip Dislocations in Children and Adolescents

Conclusions: MRI is superior to CT scan for detection of structural injuries in children and adolescents with traumatic hip dislocation. The unique structural injuries included entrapment of posterior labrum and posterior unossified acetabular fractures could be seen only at MRI. These findings will impact surgical decision making of these injuries. Level of evidence: Level IV.

DISCUSSION: The pathogenesis of frontal sinus cholesteatoma varies based on its cause (congenital vs acquired). Clinical diagnosis remains challenging but is aided by nasal endoscopy, computed tomography, and magnetic resonance imaging. Historically, FSC has been managed by total extirpation through open approaches, which can entail substantial morbidity. With sophisticated endoscopic sinus instrumentation and image guidance, FSC can be successfully treated via an endoscopic approach. Serial débridements and washouts in an outpatient setting may adequately manage the residual disease in the postoperative period. ...

AbstractSummaryWe found that the MRI T2* value is moderately negatively correlated with the bone mineral density assessed with quantitative computed tomography in evaluating osteoporosis in postmenopausal women and may have some potential in assessing severity of lumbar osteoporosis for scientific research.PurposeTo investigate the T2* quantitative measurement in magnetic resonance imaging (MRI) and its correlation with the bone mineral density (BMD) values evaluated with quantitative computed tomography (QCT) in women with postmenopausal lumbar vertebrae osteoporosis.Materials and methodsEighty-seven postmenopausal women ...

ConclusionMesenteric cysts represent a rare cause of intra-abdominal mass. Owing to low prevalence, literature is limited as is guidance on management. Careful pre-operative planning is essential so as to avoid operative complications. Imaging such as USS is of great importance; however Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) may be of more benefit, owing to the complex anatomical relations within which mesenteric cysts can present. Surgical excision is widely reported as the surgical treatment of choice for symptomatic cysts.

AbstractObjectivesThere is currently no standardized approach for assessing the depth of invasion (DOI) of oral tongue squamous cell carcinoma via diagnostic imaging. We investigated the usefulness of contrast-enhanced computed tomography (CECT) for estimating the pathological DOI of oral tongue squamous cell carcinoma by evaluating the correlation of pathological DOI with the DOIs on CECT and magnetic resonance imaging (MRI).MethodsWe retrospectively reviewed 21 of 139 patients who underwent radical surgery for primary oral tongue squamous cell carcinoma between 2009 and 2018. The 21 cases were evaluable, without dental a...

Men with clinical suspicion of PCa undergo tissue sampling and based on features including the Gleason score, Prostate Specific antigen (PSA) levels and clinical tumor (T) stage, patients are risk stratified into 6 major groups based on National Comprehensive Cancer Netwo...

çoise Kraeber-Bodere Multiple myeloma (MM) is always preceded by an initial monoclonal gammopathy of undetermined significance (MGUS) that then develops into asymptomatic or smoldering multiple myeloma (SMM), which constitutes an intermediate clinical stage between MGUS and MM. According to a recent study, risk factors for faster MGUS to MM progression include an M protein of 1.5 g/dL or more and an abnormal free light chain ratio in patients with non-IgM MGUS. Therefore, the International Myeloma Working Group (IMWG) decided to recommend whole-body computed tomography (WBCT) for patients with high-risk MGUS in ...

Abstract Magnetic resonance imaging (MRI) plays an important role in the characterization of vertebral lesions. Even if latest improvements in MRI permit to understand and suspect the nature of vertebral lesions and positron emission tomography computed tomography (PET-CT) gives information about lesion metabolism, biopsy is still needed in most cases. CT-guided percutaneous vertebral biopsy is a minimally invasive, safe and accurate procedure for definitive tissue diagnosis of a vertebral lesion. CT-guided vertebral biopsy is often the best alternative to a surgical biopsy. The purpose of this technical note is t...

Tibial slope measurements are important in guiding clinical decisions in the field of orthopedic surgery. However, there are multiple techniques across different medical imaging modalities and little is known about its impact on result and validity of the measurement. Therefore, the purpose of this study was to compare tibial slope measurements from lateral radiographs, magnetic resonance imaging (MRI) and computed tomography (CT) scans in order to better assess the clinical significance of measured tibial slope values.

CONCLUSIONS: Careful implementation of hybrid medical imaging can clearly improve the quality of the diagnosis in cancer patients and even increase the quality of care for cancer patients. Close interdisciplinary collaboration is essential to optimize therapeutic strategies for each patient. PMID: 32052117 [PubMed - as supplied by publisher]
