Phase-Resolved Functional Lung MRI for Pulmonary Ventilation and Perfusion (V/Q) Assessment05:56

Phase-Resolved Functional Lung MRI for Pulmonary Ventilation and Perfusion (V/Q) Assessment

2.4K
Here, we describe the implementation of phase-resolved functional lung MRI as a contrast-agent-free proton MR technique for the assessment of pulmonary ventilation and perfusion dynamics. Validated and applicable across different field strengths and age groups, it could enhance clinical decision-making in the future by aiding in disease quantification and therapy...

Acetylcholine Re-Challenge After Intracoronary Nitroglycerine Administration

1.7K
This protocol presents the acetylcholine rechallenge after nitroglycerine as an add-on procedure to spasm provocation testing. The purpose of this technique is to unmask co-existing microvascular spasm in patients with epicardial spasm and to assess the protective efficacy of nitroglycerine on a per-patient level to guide medical...

Three-Dimensional Phase Resolved Functional Lung Magnetic Resonance Imaging

1.1K
Three-dimensional (3D) phase-resolved functional lung (PREFUL) is a functional magnetic resonance imaging (MRI) technique that allows for quantification of regional ventilation of the whole human lung volume, using tidal breathing and contrast-agent free acquisition for 8 min. Here, we present an MR protocol to collect and analyze 3D PREFUL imaging...

Diagnostic Ultrasound Imaging of Mouse Diaphragm Function

16.6K
Diagnostic ultrasound imaging has proven to be effective in diagnosing various respiratory diseases in human and animal subjects. We demonstrate a comprehensive ultrasound protocol utilized by Dr. Zuo's lab to analyze diaphragm kinetics specifically in mouse models. This is also a non-invasive research technique which can provide quantitative information on mouse respiratory muscle...

Area of Science:

  • Pulmonology
  • Radiology
  • Pathology

Background:

  • Elderly female patient presented with a two-month history of progressive dyspnea on exertion and productive cough.
  • Initial investigations included imaging, which revealed a miliary nodular pattern in both lungs.

Observation:

  • The patient underwent an extensive diagnostic workup to explore various potential pathological processes.
  • Despite comprehensive evaluation, the underlying condition proved to be ultimately lethal.

Findings:

  • The case highlights the diagnostic challenges posed by a miliary nodular pattern on lung imaging.
  • A review of common and uncommon etiologies presenting with dyspnea and cough is provided.

Implications:

  • This educational case report aims to enhance understanding of diagnostic strategies for complex respiratory presentations.
  • It emphasizes the importance of a thorough diagnostic thought process when faced with rare or severe lung pathologies.
