Novel Imaging Technique to Assess Cervical Cancer
Study Details
Study Description
Brief Summary
This study will test a new type of DCE (dynamic contrast-enhanced) MRI (magnetic resonance imaging) to see whether, compared with traditional MRI, it produces better images that provide more information about tumors, which may help doctors make better decisions about treating women who have cervical cancer.
MRI is commonly used to detect and evaluate many types of cancer, but its slow processing speed and the risk that images will be blurred if the patient moves inside the scanner can limit its use in clinical practice. DCE MRI is a new imaging technique that uses additional computer processing to collect information continuously during scanning, which produces more detailed images faster than traditional MRI, which reduces the risk of movement-related blurring and provides important information about tumor activity.
The DCE MRI scan in this study will be done in a standard MRI scanner, using a contrast agent (gadobutrol; Gadavist®) that has been approved by the FDA.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: DCE-MR images with Gadobutrol (GBCA) 10 volunteers will undergo a single DCE-MRI of the normal cervix to fine-tune parameters and test the performance of reconstruction and quantification algorithms. Goldenangled radial LAVA data will be continuously acquired for 5 minutes and the contrast agent will be injected intravenously after 1 minute (same contrast agent and injection rate. 60 cervical cancer patients will be enrolled (inclusion criterion: newly diagnosed FIGO stage IB2-IVA cervical cancer scheduled for standard of care pelvic MRI for staging). Data from 30 of the patients will be used to assess repeatability; DCE-MRI will be acquired at baseline and repeated 48 hours (+/- 24 h) later (no therapy between the 2 scans). Data from the other 30 patients will be used to document treatment induced changes in DCE-MRI; patients in this group will undergo DCE-MRI at baseline and repeated after 2 weeks (+/- 3 days) of completion of chemoradiation treatment. |
Drug: Gadobutrol
Each patient will undergo 3 Gadavist injections. The intravenous injection of the GBCA Gadobutrol (Gadavist, Bayer Healthcare) at 0.1 mL/kg body weight (0.1 mmol/kg), administered as a bolus at a flow rate of approximately 2 mL/s. Each volunteer will undergo 1 and each patient 2 research Gadobutrol injections (the 3 injections mentioned in the protocol for patients is to account for the fact they will have had 1 injection as part of their standard of care, but the study only includes 2 research injections).
Diagnostic Test: MRI
All subjects will be imaged on the same 3T MRI scanner (GE Healthcare, USA) at MSK for all examinations. For SA1, subjects will undergo a single research DCE-MRI exam. Patients in SA2 will undergo a standard of care pelvic MRI at baseline (which includes DCE-standard) in accordance with standard clinical operating procedures at MSK.

Outcome Measures
Primary Outcome Measures
- assess changes in Ktrans value [baseline]
Each MRI sequence will have a DCE-MRI quantitative metric Ktrans value for each of 2 independent readers. The Ktrans value will be generated from the ROIs placed independently by each radiologists using dedicated software
- assess changes in Ktrans value [48 hours]
Each MRI sequence will have a DCE-MRI quantitative metric Ktrans value for each of 2 independent readers. The Ktrans value will be generated from the ROIs placed independently by each radiologists using dedicated software
