Comparison of magnetic resonance imaging and ultrasound in evaluating follicular and endometrial development throughout the normal cycle

Dynamic contrast-enhanced MR imaging to assess physiologic variations of myometrial perfusion

“…Some authors have suggested that this increase in contractility of the inner myometrium before ovulation is involved in sperm migration [45,46]. These modifications reinforce the role of the vascularisation of the inner myometrium in the implantation process [47,48] and are in keeping with 3D power Doppler angiography (3D-PDA) showing similar chronological variations in blood flow [7,8]. We noted also a reduced F and V b concomitant with a lengthening of Dt in the immediate post-ovulatory period, in keeping with the cyclic local hypoxia [49].…”

The pathophysiology of uterine adenomyosis: an update

“…Cyclical changes in the JZ as seen by MRI, together with the peristaltic waves seen by videosonography, directly demonstrate that this layer is influenced by steroids (68)(69)(70). Steroid hormones have also been implicated in the pathogenesis of uterine adenomyosis, and local rather than systemic hyperestrogenism may be implicated (71).…”

Imaging features of adenomyosis

“…Considerable variation in the normal thickness of the JZ has been reported, with a mean thickness ranging from 2 to 8 mm (Lee et al, 1985;Wiczyk et al, 1988;Mitchell et al, 1990;Brown et al, 1991;Reinhold et al, 1996). The normal range of JZ thickness is relevant to our discussion, since abnormal widening or silhouetting of the JZ is one of the MR imaging features associated with adenomyosis.…”
