Routine magnetic resonance imaging (MRI) using surface coils can reveal incidental peripheral lesions. Careful evaluation of these unexpected findings in deeper body regions is crucial for comprehensive patient care.

Area of Science:

  • Radiology and Medical Imaging
  • Neuroradiology
  • Diagnostic Imaging

Background:

  • Neuroradiological magnetic resonance imaging (MRI) examinations frequently utilize surface coils.
  • Surface coils have a reduced field-of-view and rapid signal drop-off, potentially limiting visualization of deeper structures.
  • Incidental findings outside the primary area of interest are common in medical imaging.

Purpose of the Study:

  • To review incidental peripheral lesions detected during neuroradiological MRI examinations performed with surface coils.
  • To highlight the importance of evaluating unexpected findings in regions beyond the primary imaging target.
  • To emphasize the need for careful attention to peripheral and deeper anatomical areas during routine evaluations.

Main Methods:

  • Review of neuroradiological MRI examinations conducted with surface coils.
  • Identification and categorization of incidentally discovered peripheral lesions.
  • Analysis of lesion locations relative to the primary examination site.
  • Main Results:

    • Intracranial metastases were found during orbital examinations.
    • Cerebellar and thyroid lesions were identified during cervical spine examinations.
    • Abdominal aneurysms (dissecting and saccular), renal, and intrapelvic abnormalities were detected during lumbar spine examinations.

    Conclusions:

    • Incidental peripheral lesions are frequently encountered in neuroradiological MRI with surface coils.
    • These findings span various anatomical locations, including intracranial, cervical, and abdominal regions.
    • Routine evaluation protocols should incorporate careful attention to peripheral and deeper body regions due to the limitations of surface coil imaging.
