Still a public area, but the interface between unregulated Zone I and the strictly controlled Zones III and IV. MR safety screening typically occurs here under supervision. An area near the magnet room where the fringe, gradient, or RF magnetic fields are sufficiently strong to present a physica...
Which statement about ACR Safety Zone 4 is true? Accompanying family members should never be allowed access to Zone 4. Zone 4 is synonymous with the room containing the MR scanner. Zone 4 is includes the scanner, the operator's console, and equipment room (where gradient amplifiers are ...

MRI/TRUS融合引导穿刺与经会阴饱和穿刺比较,由融合引导穿刺排他性GS ≥3+4 PC检出率为20.9%,而单独由SB检出率仅12.8%[12]。Valerio等发表了一项总计纳入14篇文献的系统综述表明,MRI/TRUS融合穿刺检可从单独标准穿刺漏诊病例中检出平均9.1%(5-16.2%)临床有意义癌症[53]。相反,标准穿刺可从MRI/TRUS融合引导穿刺...
-Level 2 personnel are those with extensive training in MRI safety, including a vast knowledge of the main magnetic field as well as the RF and gradient fields, and the risks and biological effects of these three magnetic fields. ACR recommended Zone signage for the MR suite: ...
