MRI Safe for Patients With Neurovascular Stents

By Karla Gale

SAN DIEGO (Reuters Health) Apr 07 - Physicians should not withhold any type of magnetic resonance imaging just because the patient has a neurovascular stent, according to a presentation at the American Academy of Neurology 58th Annual Meeting here in San Diego.

"We now have tons of patients with stents in their brains," Dr. Camilo R. Gomez told Reuters Health. "We've been told by radiologists for many years that you cannot do MRI in these people. But I don't believe it, and now we've proven it."

Other than safety issues, there are also concerns that image quality might be compromised, he added.

Dr. Gomez, from the University of Alabama at Birmingham, and his colleagues reviewed the records of 24 patients previously treated with neurovascular stents and who underwent magnetic resonance angiography in a 3.0 Tesla system.

There were no side effects reported for any of the patients.

All of the stents displayed metallic susceptibility artifacts. There were 12 cases of total signal loss and 5 with downstream signal degradation. Total image loss was associated with intracranial stents and stents made of stainless steel.

Source image analysis correction was possible in 13 of these cases.

"If there is an indication for MRI, there is no reason from a safety point of view to avoid it," Dr. Gomez concluded.

Несовсем ясно, можно ли эти данные экстраполировать на клипсы аневризм, но, главное, что нет сообщений о смещении металлических стентов или возникновении электрических разрядов даже на томографах с силой поля 3 Тл.

Не знаю, как со стентами в сонных, но с коронарными спокойно делают МРТ через месяц после имплантации.
