Purpose: We describe the presenting characteristics and hospital course of 11 novel coronavirus (COVID-19) patients who developed spontaneous subcutaneous emphysema (SE) with or without pneumomediastinum (SPM) in the absence of prior mechanical ventilation.
Materials And Methods: A total of 11 non-intubated COVID-19 patients (8 male and 3 female, median age 61 years) developed SE and SPM between March 15 and April 30, 2020 at a multi-center urban health system in New York City. Demographics (age, gender, smoking status, comorbid conditions, and body-mass index), clinical variables (temperature, oxygen saturation, and symptoms), and laboratory values (white blood cell count, C-reactive protein, D-dimer, and peak interleukin-6) were collected.
Purpose: Study impact of F-18 FDG PET/CT on initial staging, restaging, and evaluating treatment response (ETR) in bone and soft tissue sarcomas (BSTS), focusing on discrepancy between CT and PET portions.
Patients And Methods: Ninety-three BSTS patients having 204 F-18 FDG PET/CT studies were retrospectively reviewed. They were divided into 4 groups.
Objective: Our objective was to present a method of performing thoracolumbar MRI with intervertebral disk pressure at 150 kPa without the patient being seated.
Conclusion: Spine MRI with compression is more physiologic and will produce a higher yield than standard supine MRI.
Purpose: To evaluate the impact of F-18 fluorodeoxyglucose (FDG) positron emission tomography with fused computerized tomography (PET/CT) in comparison with same day contrast enhanced CT (CE-CT) in breast cancer management.
Method: Seventy studies in 49 breast cancer patients, 17 for initial and 53 for restaging disease were included. All patients underwent PET/CT for diagnostic purposes followed by CE-CT scans of selected body regions.
