Expert alert: Are CT scans safe?
ROCHESTER, Minn. — With questions lingering about the safety of medical imaging and the radiation that is used in some of those tests, Mayo Clinic radiation safety expert Cynthia McCollough, Ph.D., wrote a paper that provides clear answers that she hopes will allay patients’ fears. Dr. McCollough wrote “Answers to Common Questions About the Use [...]
ConclusionLipoma of the left mesocolon is exceptional. Radiological examinations provide most arguments to suggest lipoma. However the organ’s diagnosis is provided by surgical exploration and the certainty diagnosis by pathological examination. Treatment is surgical.
ConclusionPrompt diagnosis with thoracic drainage and a damage control treatment plan might lead to good prognosis for patients with this rare and potentially fatal condition.
Advances in technology have always had the potential and opportunity to shape the practice of medicine, and in no medical specialty has technology been more rapidly embraced and adopted than radiology. Machine learning and deep neural networks promise to transform the practice of medicine, and, in particular, the practice of diagnostic radiology. These technologies are evolving at a rapid pace due to innovations in computational hardware and novel neural network architectures. Several cutting-edge postprocessing analysis applications are actively being developed in the fields of thoracic and cardiovascular imaging, includi...
Novel therapeutic options in chronic obstructive pulmonary disease (COPD) require delicate patient selection and thus demand for expert radiologists visually and quantitatively evaluating high-resolution computed tomography (CT) with additional functional acquisitions such as paired inspiratory-expiratory scans or dynamic airway CT. The differentiation between emphysema-dominant and airway-dominant COPD phenotypes by imaging has immediate clinical value for patient management. Assessment of emphysema severity, distribution patterns, and fissure integrity are essential for stratifying patients for different surgical and end...
Conclusions: Our study demonstrates that a small number of patients sustain cortical impaction of the posterosuperior acetabular cortical surface along with their posterior wall acetabular fracture-dislocation. Although uncommon, preoperative imaging should be scrutinized to identify this clinical entity. As part of the preoperative plan, the surgeon can anticipate the cortex available for reduction verification and whether any additional steps or altered surgical approaches are needed to achieve an anatomical reduction. Level of Evidence: Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.
Conclusions: Fracture energy positively correlates with Sanders classification for DIACFs, which can be used to identify more severe fractures at greater risk of progressing to PTOA. Level of Evidence: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
ConclusionOur patient was surprisingly still alive after metastatic disease was diagnosed 10 years ago and she had no major complaint other than a draining mass on her neck. Our primary aim by sharing this case is to underline potential renal metastasis from papillary thyroid carcinoma. In other words, when approaching primary renal tumors, possible distant metastases of other organs nee d to be kept in mind for differential diagnosis. In addition, it should be noted that if managed appropriately, the long-term survival in patients with papillary thyroid carcinoma with multiple organ metastases could be encouraging.
AbstractBackgroundScrew misplacement incidence can be as high as 15 –30% in spine deformity surgery, with possible devastating consequences. Some technical solutions to prevent misplacement require expensive devices. MySpineTM comprises a low-dose CT scan of the patient ’s spine to build a virtual model of the spine to plan the screw trajectories and a 3D-printed patient-specific guide system to prepare the screw trajectories and to implant the screws in the vertebrae in order to increase reproducibility and safety of the implants. The aim of this open-label, sin gle-center, prospective randomized clinical tria...
ConclusionsPDH are not usually associated with specific symptoms and signs; thus, they constitute a diagnostic challenge, requiring a high level of knowledge and clinical suspicion. Undoubtedly, CT scan of the abdomen is the gold standard diagnostic tool. Their operative repair is mandatory, with the laparoscopic approach demonstrating significant advantages over the open repair, seeming to be the optimum treatment strategy.
Sarcopenia is a predictor of mortality in elderly patients. Masseter area (MA) reflects sarcopenia in trauma patients. It was hypothesised that MA and Masseter density (MD) could be evaluated reliably from pre-operative computed tomography angiography (CTA) scans and that they predict post-operative survival in carotid endarterectomy (CEA) patients.
