Magnetic resonance imaging (MRI) and angiography offer high confidence in diagnosing haemangiomas. For incidental findings, ultrasound (US) follow-up is sufficient, while high-risk patients benefit from immediate MRI after initial US.

Area of Science:

  • Radiology
  • Medical Imaging
  • Oncology

Background:

  • Haemangiomas are benign vascular tumors requiring accurate diagnosis.
  • Differentiating haemangiomas from other lesions can be challenging.
  • Imaging modality choice impacts diagnostic confidence.

Purpose of the Study:

  • To evaluate radiologist confidence in diagnosing haemangiomas using various imaging techniques.
  • To compare diagnostic confidence between incidental and oncologic (high-risk) populations.
  • To establish optimal imaging pathways for haemangioma diagnosis.

Main Methods:

  • Retrospective analysis of 92 confirmed haemangioma cases.
  • Assessment of diagnostic confidence using ultrasound (US), computed tomography (CT), angiography, and magnetic resonance imaging (MRI).

  • Comparison of confidence levels across different patient groups (incidental vs. oncologic) and lesion sizes.

    • Main Results:

    • MRI (88-93%) and angiography (85-91%) demonstrated the highest diagnostic confidence in both groups.
    • Ultrasound showed lower confidence (44% incidental vs. 11% oncologic).
    • Dynamic contrast bolus CT confidence was higher in incidental (76%) versus oncologic (48%) groups.

    Conclusions:

    • In high-risk populations, MRI is recommended directly after initial US for haemangioma diagnosis.
    • For incidental haemangioma findings with typical features, 6-month US follow-up is adequate.
    • Imaging modality selection should be tailored to patient risk stratification for optimal haemangioma diagnosis.
