Our results demonstrate that cerebral perfusion is significantly altered in COPD patients. Hypoxemic patients showed more deterioration in cerebral perfusion and cognitive performance than nonhypoxemic patients. The relationship between decreased perfusion and cognitive impairment and the clinical significance of these results require further studies in larger populations.

Renal function improves after pyeloplasty with regard to the initial level of split renal function in adult obstructed kidneys. Improvement may not be observed especially in patients with DRF less than 30%.

Early diagnosis of neurological involvement in BD is important in reducing or preventing complications. Cranial MRI and EEG were found to be useful for detecting subclinical neurological abnormalities in patients with Behçet's disease.

The renal cortical defects present at 6 months have a high rate of resolution later during follow-up. DMSA scintigraphy performed 12 months after the infection provides more reliable data regarding persistence of renal cortical lesions.

Bone SPECT results were found to be correlated with the stage of CRS. Poorer subjective response was observed in patients with positive SPECT.
