Contrast-enhanced magnetic resonance angiography of the lower extremities: standard-dose vs. high-dose gadodiamide injection.

Purpose: To compare the efficacy and safety of two different doses (0.1 and 0.3 mmol/kg of body weight [BW]) of gadodiamide for contrast-enhanced magnetic resonance angiography (ce-MRA) of the lower extremities with intraarterial digital subtraction angiography (IA-DSA).

[Prospective study to compare high-resolution computed tomography and magnetic resonance imaging in the detection of pancreatic neoplasms: use of intravenous and oral MR contrast media].

Purpose: To compare thin-section hydro-CT and MRI in the detection of pancreatic neoplasms. Evaluation of an oral, superparamagnetic contrast agent (OMP) for pancreatic MRI.

Material And Methods: 45 patients with suspected pancreatic neoplasms were examined with consecutive thin-section helical CT (Hydro-CT, 3/6/3, 130 ml Ultravist, Schering) and MRI (1.

[Clinical value of native and contrast enhanced MRI in staging prostatic carcinoma before planned radical prostatectomy].

Purpose: To assess the clinical value of MRI with and without contrast agent in the staging of prostatic carcinoma. Relevance for surgical management.

Methods: 60 patients with carcinoma proven by biopsy or suspected prostatic carcinoma were evaluated with MRI.
