Purpose: To determine the cost-effectiveness of promptly performing myocardial perfusion (MP) imaging with single photon emission computed tomography (SPECT) in patients presenting to the emergency department with unexplained chest pain.
Materials And Methods: Fifty patients with unexplained chest pain underwent MP imaging with SPECT and technetium-99m sestamibi. The cardiologists' management plans before and after receipt of imaging findings were compared. Costs were determined from analysis of comparable admissions for the 6 months before the start of the study.
Results: The cardiologists' confidence in their clinical diagnosis significantly increased with use of MP imaging (P<.0001). MP imaging results altered management decisions in 34 patients. Twenty-nine patients were sent home on the basis of imaging findings. None of the patients with a normal MP image experienced a serious adverse cardiac event. The total savings to the hospital was $39,296, or $786 per patient.
Conclusion: Performing MP imaging in patients with unexplained chest pain while in the emergency department is cost-effective.

Pleuropulmonary blastoma (PPB) is an uncommon malignant neoplasm occurring in infants. The disease is intimately linked to mutations in the Dcr-1 homolog and ribonuclease type III (DICER1) genes. Imaging techniques are crucial for diagnosing PPB, yet distinguishing PPB from other pulmonary masses proves challenging.

Dynamic digital radiography (DDR) is a recent imaging technique that allows for real-time visualization of thoracic and pulmonary movement in synchronization with the breathing cycle, providing useful clinical information. A 46-year-old male, a former smoker, was evaluated for unexplained dyspnea and reduced exercise tolerance. His medical history included a SARS-CoV-2 infection in 2021.

Sjogren's syndrome is an autoimmune condition characterized by infiltration of exocrine glands but, in rare cases, can have extraglandular involvement with pleural effusion being an exceedingly rare form. Here we present a case of Sjogren's pleuritis resulting in pleural effusion, a rare initial presentation for Sjogren's syndrome. A woman in her 20s presented to the emergency department after a recent hospitalization for pneumonia, pleural effusion, and pulmonary embolism.
