This technique intentionally uses free breathing scanning rather than breathholding or respiratory triggering to visualize (moving) visceral organs and their lesions.
Therefore, instead of aiming to reduce image blurring, it can be more advantageous to improve the SNR in DWI by means of free breathing scanning, which allows thin slice acquisitions and multiple-slice excitations for volumetric imaging.
In 2004, Takahara et al. reported a unique concept of whole-body DWI using the short tau inversion recovery (STIR -EPI STIR -EPIand free breathing sequence (diffusion-weighted whole-body imandng with background body signal suppression: DWIBS).
All volumes were delineated on each breath-hold scan and free-breathing scan.
Nevertheless, there is a perspective that the method of choice for morphologic and functional assessment of acute pulmonary embolism in the very near future might be a non-contrast-enhanced free breathing MR scan of 10 15 min.
3. UCLA - Free Guided Meditations Organization: UCLA Mindful Awareness Research Program Topic(s): Breathing, Body Scan, Sleep, Dealing with Difficulty, and more Duration: Mostly less than 10 minutes.
During the RR elicitation in the weekly session, the subject was guided through a RR sequence including: diaphragmatic breathing, body scan, as well as mantra and mindfulness meditation, while subjects passively ignored intrusive thoughts.
Rocking side to side on the soles of my shoes, I focused on the rhythm of my breathing and scanned the stands, watching them fill, one red pixel at a time.
We demonstrate on the alignment of 250 nodules, that the algorithm is robust to changes caused by cancer progression and differences in breathing states, scanning procedures, and patient positioning.
To minimize breathing artefacts, scans were performed in inspiration after appropriate instruction of the participants.
