Evaluation of Safety and Efficacy of ProHance in Pediatric Patients <2yrs

The purpose of this study is to retrospectively enroll children younger than 2 years of age
who have undergone brain or spine MRI with 0.1 mmol/kg PROHANCE and to gather safety data as
well as to collect MR images for a prospective blinded read to evaluate the efficacy of
PROHANCE in terms of visualization and enhancing properties.

The study will be conducted in 4-8 sites in the United States and Europe. It is estimated
that 120 patients will be enrolled to provide 108 evaluable patients.

Three radiologists unaffiliated with enrolling centers (blinded readers), blinded to the
patient's identity and clinical profile will independently evaluate the MRI images. The
efficacy analysis will be primarily based on the blinded reader evaluations.

Imaging conditions will represent those in routine clinical practice, inclusive of pre and
post-contrast images.

Inclusion Criteria:

- Is male or female and was younger than 2 years of age at the time of the MRI with
PROHANCE injection at the dose of 0.1 mmol/kg (±25% in volume administered).

- Has demographic information, reason for the ProHance-enhanced MR examination, relevant
medical history, final diagnosis, and safety data available.

- Has documented known or highly suspected enhancing disease of CNS (brain/spine) and
previously underwent a cranial or spinal MR examination requiring an injection of
PROHANCE contrast agent.

- Has both predose and postdose T1 SE/FSE and/or GRE and T2 SE/FSE, and FLAIR MR images
(when available) for submission to Bracco or designee to be evaluated in a fully
blinded read.

- Has complete information on the imaging protocol used for the ProHance-enhanced MR
exam including type of exam (brain or spine), MR scanner and field strength (1.0, 1.5
or 3.0 Tesla)

- Has a documented dose of PROHANCE administered for their MRI exam and/or the volume
(mL) and weight of the patient available to be used to calculate the exact dose of
PROHANCE that was administered.

Exclusion Criteria:

• Exclude a patient from this study if the patient does not fulfill all of the inclusion
criteria.
