MRI in Diagnosing Solid Tumors of the Eye and Orbit
Dynamic Contrast Enhanced Magnetic Resonance Imaging for Non-Invasive Diagnostic Work-Up in Solid Tumors of the Eye and Orbit.

Intervention / Treatment
Detailed Description
PRIMARY OBJECTIVES:
I. To determine the feasibility of DCE-MRI (dynamic contrast enhanced magnetic resonance imaging) as non-invasive imaging tool to image contrast enhancement in ocular and orbital tumors.
II. To compare contrast enhancement and its distribution within orbital tissue. III. To assess potential differences in contrast enhancement which help to characterize malignant lesions as well as discriminate these from benign tissue.
IV. To compare image characteristics between clinical high field end ex-vivo ultra high field magnetic resonance (MR) imaging.
V. To correlate imaging findings with obtained histology by comparing contrast enhancement parameters, e.g. maximum signal intensity, to histology characteristics, e.g. vascular density.
OUTLINE:
Patients undergo DCE-MRI.
After completion of study treatment, patients are followed up every 6 months for up to 5 years.

Participation Criteria
Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- The patient has an orbital mass which needs further diagnostic evaluation before treatment or for monitoring
- Able to give informed consent
- Return for follow-up visits
Exclusion Criteria:
- Patients with a lesion < 2 mm
- The patient should not participate in this study is any of the following applies to the patient: the patients has a pacemaker, metallic cardiac valve(s), magnetic material such as surgical clips, implanted electronic infusion pumps or any other condition that would interfere with the MRI, the patient has a stent somewhere in the body, the patient has a history of allergic reaction to any metals, contrast agents, x-ray dyes, the patient has claustrophobia
- Patients cannot be pregnant and prisoners will not be considered for the study
Exposure to gadolinium-based contrast agents increases the risk for nephrogenic systemic fibrosis (NSF) in patients with acute or severe renal dysfunction; therefore, patients with the following conditions are excluded from the study:
- Acute or chronic severe renal insufficiency (glomerular filtration rate < 30 mL/min/1.73 m^2)
- Acute renal dysfunction due to the hepato-renal syndrome or in the perioperative liver transplantation period
In order to identify subjects at risk for the development of NSF, the American College of Radiology (http://acr.org) recommends obtaining a medical history and a glomerular filtration rate (GFR) assessment within six weeks of MR imaging in the following patients:
- Renal disease (including solitary kidney, renal transplant, renal tumor)
- Age > 60
- History of hypertension
- History of diabetes
- History of severe hepatic disease/liver transplant/pending liver transplant
- All subjects providing written informed consent will complete the subject history and screening form prior to MR imaging; the form will be reviewed to determine whether the subject is at risk as defined above and the availability of an estimated glomerular filtration rate (eGFR) within six weeks of anticipated MR imaging; an eGFR result greater than six weeks prior to the MRI imaging date will be repeated and evaluated for renal function; subjects with an eGFR of < 30 mL/min/1.73 m^2 will be excluded from the study

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Dynamic contrast-enhanced MRI
Patients undergo Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI)
|
Studies will be performed on standard clinical MR Systems which are available on Campus.
With the proposed imaging technique, we are able to acquire a 3D volume covering the orbit with a temporal resolution of approximately 15s.
The affected eye will be immobilized to reduce motion artifacts.
A routinely used MR contrast agent will be administered in a dose of 0.1mmol/kg bodyweight.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Diagnosis of benign vs. malignant lesions using DCE-MRI
Time Frame: Up to 5 years
|
Crude comparisons between the groups of patients (benign vs. malignant) will be performed using a one-way ANOVA or nonparametric Wilcoxon Rank Sum test, where appropriate.
Outliers and influential covariate patterns will be identified using diagnostic plots.
Depending on the complexity of the models, exact methods may be necessary.
|
Up to 5 years
|
Improved characterization of different malignant tumor types
Time Frame: Up to 5 years
|
Logistic regression models will be applied to determine the factors most predictive of malignancy using forward selection methods described in Hosmer-Lemeshow goodness-of-fit test as well as the area under the Receiver-Operator Characteristic (ROC) curve.
Outliers and influential covariate patterns will be identified using diagnostic plots.
Depending on the complexity of the models, exact methods may be necessary.
