We investigate the e!ect of the width of ventilation}perfusion distributions on arterial blood oxygen content. We assume that the perfusion within the alveolar volume is a continuous function of ventilation}perfusion ratio, known as the continuous ventilation}perfusion distribution, and then write d
## Abstract A new method is presented for quantitative mapping of ventilation‐to‐perfusion ratios (V~A~/Q) in the lung: MRI of the ^19^F longitudinal relaxation time (__T__~__1__~) of an inert fluorinated gas at thermal polarization. The method takes advantage of the dependence of the ^19^F __T__~_
## Abstract ## Purpose To study arterial spin labeling (ASL) MRI techniques and to investigate various problematic issues that still hinder the accurate and robust quantitative analysis of ASL data. ## Materials and Methods A pulsed‐ASL (PASL) sequence was implemented on a 3‐T imaging system and
