Whole body MRI will be performed in patients with neurofibromatosis Type 1


To determine the total tumor load (neurofibroma) and to diagnose plexiform neurofibromas or malignant peripheral nerve sheath tumors. All patients will be scanned two years after the baseline whole body MRI to investigate to investigate the changes of total tumor load.

PURPOSE 2: added value of diffusion weighted imaging in diagnosis of high-risk neurofibromas

PURPOSE 3 : to determine the apparent diffusion coefficient of the malignant nerve sheath tumors and neurofibroma.

PURPOSE 4 : correlation between histopathology of the surgically resected neurofibroma/malignant nerve sheath tumors and MRI findings

Further study details as provided by Universitaire Ziekenhuizen Leuven:

Primary Outcome Measures:
  • Estimation of total tumor load and diagnosis of high-risk neurofibromas [ Time Frame: 1 month ]
    Estimation of the total tumor load of neurofibromas with whole body MRI (head to knee). Diagnosis of high risk neurofibroma in the chest, abdomen, pelvis, and extremities with T2-weighted sequence and diffusion weighted sequence.

Secondary Outcome Measures:
  • To diagnose high-risk neurofibroma [ Time Frame: 2 months ]
    Some patients with neurofibromatosis have lesions, pre-malignant or malignant neurofibromas. Additional imaging (PET-CT), a biopsy or surgical treatment is necessary in combination with histopathology of the lesion.

Estimated Enrollment: 30
Study Start Date: December 2010
Estimated Study Completion Date: January 2014
Estimated Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Neurofibromatosis 1

All patients diagnosed with neurofibromatosis type 1. GROUP 1:ADDITIONAL IMAGING OR SURGERY There will be patients with high-risk neurofibromas (potential malignant). These patients will underwent additional examinations or surgery (outside this study). Follow-up MRI within 2 years (study MRI )


No suspicious lesions at MRI. Follow-up within 2 years(Study MRI).

Other: Additional imaging or surgery
No specific intervention is necessary. If a suspicious lesion is diagnosed on MRI, further investigation will be planned (PET-CT or surgery - biopsy)
