GOLD grade-specific characterization of COPD in the COSYCONET multi-center trial: comparison of semiquantitative MRI and quantitative CT.
Eur Radiol

Department of Diagnostic and Interventional Radiology, University Hospital of Heidelberg, Heidelberg, Germany.
Objectives: We hypothesized that semiquantitative visual scoring of lung MRI is suitable for GOLD-grade specific characterization of parenchymal and airway disease in COPD and that MRI scores correlate with quantitative CT (QCT) and pulmonary function test (PFT) parameters.
Methods: Five hundred ninety-eight subjects from the COSYCONET study (median age = 67 (60-72)) at risk for COPD or with GOLD1-4 underwent PFT, same-day paired inspiratory/expiratory CT, and structural and contrast-enhanced MRI. QCT assessed total lung volume (TLV), emphysema, and air trapping by parametric response mapping (PRM, PRM) and airway disease by wall percentage (WP).
Pulmonary tuberculosis presenting as a hilar mass.

Tuberculosis (TB) is a great mimicker due to its various unusual and atypical presentations. Mass-like lesions in thoracic radiology may raise the suspicion of lung malignancy. A man in his early 50s complained of cough, low-grade fever and dyspnoea.

A nulliparous woman in her late 30s with a history of pericardial patch repair for atrial septal defect and completed treatment for pulmonary tuberculosis 9 years ago presented with chest pain, breathlessness and abdominal pain. Radiological imaging revealed right-sided pneumothorax, pneumopericardium and pneumoperitoneum for which an intercostal drain (ICD) was placed. A contrast-enhanced CT of the abdomen showed a distal stomach perforation, which was managed conservatively.

This review presents current opinions on an uncommon condition called catamenial pneumothorax (CP), which is usually associated with thoracic endometriosis syndrome (TES). TES is characterized by the presence of endometriotic lesions in pleura and lung parenchyma and presents with various clinical signs and symptoms, including catamenial pneumothorax. Their diagnosis is often delayed.

LSF is assessed using Tc macroaggregated albumin ( Tc-MAA) imaging, but this approach adds risk, complexity, and expense to the treatment planning. This study investigates the potential of Contrast-Enhanced Computed Tomography (CECT) as a non-invasive alternative for LSF estimation.
