Purpose: 2D cine phase contrast (PC)-MRI is a standard velocimetry for the superior mesenteric artery (SMA); however, the optimal localization of the measurement plane has never been fully discussed previously. The purpose of this Institutional Review Board approved prospective and single arm study is to test whether flow velocimetry of the SMA with combined use of 2D cine PC-MRI and meal challenge is dependent on the localizations of the measurement planes and to seek optimal section for velocimetry.
Methods: Seven healthy volunteers underwent cardiac phase resolved ECG gated 2D cine PC-MRI pre- and 30 min post-meal challenge at three measurement planes: proximal, curved mid section and distal straight section of the SMA at 3T.
Article Synopsis
- - A 90-year-old man presented with painful swelling in his right ear, facial nerve paralysis, and signs of meningitis, ultimately diagnosed with Ramsay Hunt syndrome and varicella-zoster virus meningoencephalitis after testing positive in his cerebrospinal fluid.
- - Imaging showed lesions in his brain, and treatment with intravenous acyclovir improved his meningitis symptoms but he unexpectedly died 16 days later from gastrointestinal hemorrhage.
- - Autopsy revealed significant lymphocytic infiltration in the brain's meninges and specific regions, highlighting that encephalitis from varicella-zoster virus is a rare but serious condition that can lead to severe complications.
Anti-neutrophil cytoplasmic antibodies (ANCA) in sera from 52 patients with rheumatoid arthritis (RA), including 9 patients with malignant RA (MRA) and 20 healthy controls were examined by indirect immunofluorescence technique (IIF). Nine out of 52 RA patients showed positive ANCA staining. None of MRA patients had, however, ANCA in sera.
