In patients without a history of L-spine
surgery, the rate of spreading of 14 mL of injectate was 31.9% at the L2-3,54.5% at the L3-4, 80.6% at the L4-5, and 98.1% at the L5-S1 disc levels.
In this observational study, data from 590 patients who underwent L-spine
MRI at Shuang Ho Hospital, Taipei Medical University, from January 2010 to August 2010 were recorded and measured.
The data include the same three exams that were used for the primary beam exposure and two more: the supine abdomen exam, which is frequently ordered for inpatients, and the lateral spot L-spine
exam, which requires the most radiation to produce an image.
Axial load was applied using a Dynawell[R] (Dynawell, Int., Billdal, Sweden) L-spine
(See table.) All bone parameters, including z score, T score, and L-spine
, were lower in the CAH group.
