INDICATIONS: 49 year-old patient with shortness of breath. Possible PE. Possible occupational lung disease. PROCEDURE: Consecutive axial slices were obtained without and with intravenous contrast. Bolus thin slices were performed through the pulmonary arteries. The pulmonary trunk shows no evidence for ...

Direct post-contrast arterial-phase CT is recommended in the context of suspected pulmonary embolism or superimposed bacterial pneumonia, which are the primary differential diagnoses and common complications of severe COVID-19 cases6,28. Patients with COVID-19 who meet indications for CT imaging are...
We compared the capability of PET-MR to that of same-day PET-CT to assess osseous metastases in patients with breast cancer. Methods: One hundred and nine patients with breast cancer, who underwent same-day contrast enhanced (CE)-PET-CT and CE-PET-MR, were evaluated. CE-PET-CT and CE...
With the dissemination of SPECT/CT, the range of applications has expanded from myocardial perfusion imaging to oncology indications, such as torso imaging in patients with neuroendocrine tumors (NETs), differentiated thyroid carcinomas, lymphoma, and sentinel node lymphoscintigraphy [2]. SPECT/CT imag...
