| Outline of Research at the Start |
In recent years, machine learning and deep learning has become a subject of interest for many researchers worldwide. Whereas, CNN have become a methodology of choice for analyzing medical images. In this research, we propose a CNN based approach for generating PET/CT image series for malignant tumors in pancreas in shorter scan time. The images are currently obtained during the delayed scan during the regular PET/CT imaging analysis.
|
| Outline of Annual Research Achievements |
Initial and delayed scans, also known as dual-time-point scans, are widely used in positron emission tomography/computed tomography (PET/CT) for the diagnosis and delineation of pancreatic cancer; however, their acquisition is relatively time-consuming. The purpose of this pilot study was to use neural network based method to eliminate the need of delayed PET/CT scan for diagnosis. The results obtained from our CNN-LSTM based analysis suggested that our study could obviate the need for delayed scans however validations studies are required for the clinical application of our model.

Current Status of Research Progress
4: Progress in research has been delayed.
Reason
The pilot study (Data acquisition and analysis) has been completed and the journal paper was submitted, unfortunately it could not be accepted hence we are currently correcting the manuscript and preparing for submission in other journal.
|
| Strategy for Future Research Activity |
Currently the manuscript is being prepared for this work and is to be submitted in a scientific journal.
