This measure can be used prophylactically or therapeutically depending on the aim of infusion. There is as yet no broad consensus on the precise indications for amnioinfusion, particularly regarding prophylactic amnioinfusion for oligohydramnios. This review aims to shed light on this issue and concludes that additional, well-designed studies are needed to provide data that can help clinicians choose the most appropriate procedure.

Regional relaxation has been well characterized in normal subjects using this technique, and physiological time intervals and motion wave profiles are described. In an experimental model of acute ischemia, local relaxation impairment was observed showing highly characteristic local diastolic abnormalities. Interestingly, these findings took place before any decrease in systolic motion was recordable. In a prospective clinical study, noninvasive regional DTI parameters were compared with coronary angiography to assess the feasibility and clinical value of the technique; the diagnostic accuracy is discussed in detail. Also, the association between regional diastolic parameters and global regional function as assessed by Doppler analysis of transmitral left ve...
