Muscles of the Anterior Neck01:26

Muscles of the Anterior Neck

5.3K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Arteries of the Head and Neck01:26

Arteries of the Head and Neck

3.9K
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...

Area of Science:

  • Medical Imaging
  • Magnetic Resonance Imaging (MRI)

Background:

  • Standard commercial MRI coils for head and neck imaging may have limitations in achieving simultaneous high-resolution imaging with optimal signal-to-noise ratio (SNR).
  • Neck anatomy varies, necessitating specialized coil designs for improved imaging performance.

Purpose of the Study:

  • To introduce and evaluate the concept of interchangeable neck shape-specific (NSS) coils.
  • To demonstrate that NSS coils can supplement existing commercial spine and head/neck coils.
  • To achieve simultaneous high-resolution (hi-res) head and neck imaging with high SNR.

Main Methods:

  • Two NSS coils were constructed using formers tailored to different neck shapes (medium and large).
  • A 7-channel (7ch) ladder array was built on a medium neck former, and a 9-channel (9ch) ladder array on a large neck former.
  • Both NSS coils shared an interchangeable preamp housing and were tested for compatibility with commercial coils.

Main Results:

  • The 7ch and 9ch NSS coils achieved approximately 4x and 3x SNR gains, respectively, in the carotid arteries compared to a standard 20-channel head/neck coil.
  • Negligible electromagnetic coupling was observed between the NSS coils and commercial Siemens spine (32ch) and head/neck (20ch) coils.
  • This allowed for simultaneous high-resolution imaging of the head and neck without compromising SNR.

Conclusions:

  • Supplementing commercial MRI coils with NSS coils enables uniform, simultaneous high-resolution imaging in the anterior neck.
  • High SNR is maintained in the anterior neck region while preserving the SNR of the commercial coil in the head and posterior neck.
  • NSS coils represent a viable strategy to enhance simultaneous head and neck MRI capabilities.
