Randomized Controlled Trial Comparative Study
Comparative prospective randomized study comparing conservative treatment and percutaneous disk decompression for treatment of intervertebral disk herniation.
To compare short-, intermediate-, and long-term functional results concerning pain reduction and mobility improvement between conservative therapy and percutaneous disk decompression (PDD) in patients with intervertebral disk herniations. ⋯ When compared with conservative therapy, PDD shows improved amelioration of symptoms at 12- and 24-month follow-up.

Comparative Study
Acute appendicitis in young adults: low- versus standard-radiation-dose contrast-enhanced abdominal CT for diagnosis.
To compare low and standard radiation doses in intravenous contrast material-enhanced abdominal computed tomography (CT) for the diagnosis of acute appendicitis in young adults. ⋯ Low-dose CT may have comparable diagnostic performance to standard-dose CT for the diagnosis of appendicitis in young adults.

Comparative Study
Pulmonary functional imaging: qualitative comparison of Fourier decomposition MR imaging with SPECT/CT in porcine lung.
To compare unenhanced lung ventilation-weighted (VW) and perfusion-weighted (QW) imaging based on Fourier decomposition (FD) magnetic resonance (MR) imaging with the clinical reference standard single photon emission computed tomography (SPECT)/computed tomography (CT) in an animal experiment. ⋯ This animal experiment demonstrated qualitative agreement in the assessment of regional lung ventilation and perfusion between contrast media-free and radiation-free FD MR imaging and conventional SPECT/CT.

To assess the impact on length of stay and rate of major adverse cardiovascular events of a cardiac computed tomographic (CT) angiography-guided algorithm to examine patients who present to the emergency department (ED) with low- to intermediate-risk chest pain. ⋯ Tailoring troponin measurement to cardiac CT angiography findings is safe and allows early discharge of patients with low- to intermediate-risk chest pain, resulting in reduced length of stay.

To assess the level of distress in women awaiting radiologic procedures. ⋯ Uncertainty of diagnosis can be associated with greater stress than is awaiting more invasive and potentially risky treatment.
