ExamCard purpose

This Panorama High Field Open ExamCard is used to scan the cervical spine,of patients that may have difficulty lying supine on the examination table due to reasons such as claustrophobia or pathology. The ST Extremity M coil is used.

Patient preparation

Some patients cannot be scanned in the normal supine position. Because the Panorama 1.0T is an open scanner, these patients are placed on their side, which is known as the panoramic position.

 

The ST Extremity M coil is used with one element placed around the patient's neck and the second placed posterior to the neck (see the photo below). This positioning of the coil gives a high SNR and also extends the anatomical coverage.

Note: the coil elements are perpendicular to each other with a separation of 2cm between them.

 

The patient should be made comfortable and held firmly in position using pads, pillows and/or wedges. The patient should also be positioned as straight as possible.

 

It is important to stabilize coil elements well with sandbags and/or pads.

 

Make sure the patient's shoulder, or any other body part, is not touching the upper pole. If necessary use a thinner mattress under the patient.

 

Panoramic positioning is also used to perform functional cervical spine imaging, enabling the patient to bend forward (flexion) and/or backwards (extension).
