There were 101 patients included in the analysis, of whom 78% had a perfusion deficit detected on PWI with a mean lesion volume of 47 (±59) mL. The NIH-FHV score was strongly associated with the PWI l...
The NIH-FHV score provides an estimate of the PWI lesion volume and, when combined with diffusion weighted imaging, may be helpful when trying to determine whether there is a clinically relevant diffu...

Type 2 diabetes mellitus (T2DM) is associated with altered cerebral vasoreactivity, cognitive impairment, and functional decline. Magnetic Resonance (MR) perfusion can be used to assess cerebral blood...
The study included 52 patients diagnosed with T2DM and 39 healthy individuals. The diabetic patients were classified into three groups (PRP: proliferative retinopathy, NPRP: non-proliferative retinopa...
The comparison between the T2DM group and the control group revealed that rCBF values of bilateral frontal lobes, cingulate gyrus, medial temporal lobe, thalami and right occipital lobe were measured ...
Regional hypoperfusion was encountered in most of the lobes in the T2DM group when compared with the healthy group. However, in terms of rCBF values, there was no significant difference among the thre...
Pulmonary blood flow can be assessed on ventilation-perfusion (VQ) scan with relative lung perfusion, with a 55% to 45% (or 10%) right-to-left differential considered normal. We hypothesized that wide...
We conducted a retrospective cohort study on all patients who underwent double-lung transplant in our program between 2005 and 2016, identifying patients with a wide perfusion differential of >10% on ...
Of 340 patients who met inclusion criteria, 169 (49%) had a relative perfusion differential of ≥ 10% on a 3-mo VQ scan. Patients with increased perfusion differential had increased risk of death or re...
Wide lung perfusion differential was common after lung transplant in our cohort and associated with increased risk of death, poor lung function, and CLAD onset. The nature of this abnormality and its ...
Although COVID-19 infection is associated with the increased risk of pulmonary thromboembolism (PTE), COVID-19 pulmonary lesions cause ventilation-perfusion (V/Q) patterns other than PTE. Although ext...
