This condition should be promptly recognized and treated because a delayed diagnosis may significantly reduce women's fertility and intra-abdominal bleeding may be life-threatening. Many imaging modalities play a key role in the diagnosis of acute pelvic pain from gynecological causes.

Acute COPD exacerbation: 3 T MRI evaluation of pulmonary regional perfusion--preliminary experience.

Objectives: To compare pulmonary perfusion parameters by means of dynamic perfusion magnetic resonance in patients affected by chronic obstructive pulmonary disease (COPD), during and after acute exacerbation.

Methods: Fifteen patients were successfully evaluated with perfusional MRI during an acute exacerbation of COPD and upon clinical stabilization. Inclusion criteria were a PaCO2 > 45 mmHg and respiratory acidosis (arterial blood pH < 7.
