| Suunto also recommends you to be trained in freediving technique and physiology before conducting breathhold dives. |
|
| Any breathhold diving results in some nitrogen build-up in the blood and other fast tissues. |
|
| Therefore, provided the effort involved in freediving has not been severe, there is little risk in diving after breathhold diving. |
|
| Second, patients investigated with scanner I had CMR during breathhold, while patients in the second cohort had CMR during free breathing. |
|
| First-pass perfusion imaging of the heart at rest was performed using a saturation-recovery trueFISP sequence with a parallel imaging factor of 2. This allowed for an acquisition of four slices in a single breathhold. |
|
| Critical to the accuracy and interpretability of these MDCT-derived metrics is the assurance that the lungs are scanned during a breathhold at a standardized volume. |
|
| Acquisition times can be long and prevent imaging within the time span of a single breathhold. |
