During an MRI procedure, the technologist will be able to talk to and hear the patient at all times. Anti-anxiety medication or mild sedation may be recommended if claustrophobia or anxiety during the scan is a concern. Patients who are injected with gadolinium-based contrast agents are advised...
In this technique, direct visualization of the needle, needle guide, and needle trajectory during the procedure provides a precise and versatile strategy to accurately sample suspicious lesions, improving detection of clinically significant cancers.Debora Z. Recchimuzzi...

As a result, administering intravenous agents during MRI scans becomes a complex process, often requiring conventional infusion pumps to be positioned outside the MRI room with long extension lines. This setup not only adds complexity to the procedure but also introduces potential delays in MRI diag...
To calculate the strength of the SSFP-FID and SSFP-echo signals for GRE imaging, a two-step procedure is usually followed. (An alternative procedure is described in Gyngell 1988.)First, a recursion relation is set up that equates the magnetization in adjacent TR intervals, similar to Eq. (...
Magnetic resonance imaging (MRI) is an inherently slow imaging modality, since it acquires multi-dimensional k-space data through 1-D free induction decay or echo signals. This often limits the use of MRI, especially for high resolution or dynamic imagin
Surgical procedure 手术操作 To detect csPCa, three mpMRI “components” are used: “anatomic” T2-weighted imaging, “cellular-density” diffusion-weighted imaging, and “vascularity” dynamic contrast-enhanced MRI. 为了检测csPCa,术者应用了三...
Additional ICELF procedure was performed in patients with contralateral foraminal stenosis. Upon completion of LE-ULBD, we switched to a transforaminal endoscope with a 30°, 7.3-mm-outer diameter and 171-mm-length endoscope docked at the contralateral superior articular facet ventral and distal to...
Procedure Results What is an MRI scan (magnetic resonance imaging)? An MRI scan (magnetic resonance imaging) uses magnetism and radio frequencies to create images from within the body. It is a much different technology than X-ray or CT scan because no radiation that penetrates the body is...
