Randomized Controlled Trial
Effectiveness of transforaminal epidural steroid injection by using a preganglionic approach: a prospective randomized controlled study.
To prospectively evaluate the short- and midterm effectiveness of transforaminal epidural steroid injection (TFESI) for lumbosacral radiculopathy with respect to injection level. ⋯ TFESI for lumbosacral radiculopathy with a preganglionic approach is more effective than TFESI with a ganglionic approach at short-term follow-up.

Randomized Controlled Trial Comparative Study
Pancreas: patient body weight tailored contrast material injection protocol versus fixed dose protocol at dynamic CT.
To prospectively compare the effect of a protocol with a fixed contrast material injection dose and one with a dose tailored to patient body weight on pancreatic enhancement at dynamic computed tomography (CT) of the pancreas. ⋯ The dose protocol tailored to the patient's body weight yielded satisfactory pancreatic and hepatic enhancement irrespective of patient weight.
