Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Background:

  • Positron Emission Tomography/Computed Tomography (PET/CT) is vital for diagnosing and managing serious diseases like cancer.
  • PET/CT scans utilize radioactive isotopes, such as [18F]FDG, which have short half-lives.
  • Unused radiopharmaceuticals are disposed of daily, representing significant radioactive waste.

Purpose of the Study:

  • To develop and present AppointmentPlus, a web-based system for optimizing PET/CT scan scheduling.
  • To minimize the generation of radioactive waste by reducing leftover radiopharmaceutical doses.
  • To enhance operational efficiency in Nuclear Medicine departments.

Main Methods:

  • Implementation of a web-based appointment booking system named AppointmentPlus.
  • Optimization of daily PET/CT scan schedules.
  • Focus on minimizing the quantity of radiopharmaceutical required per patient.

Main Results:

  • The AppointmentPlus system aims to significantly reduce radioactive waste from PET/CT procedures.
  • Optimization of schedules leads to more efficient utilization of short-lived radioactive isotopes.
  • Potential for cost savings and improved resource management in nuclear medicine.

Conclusions:

  • AppointmentPlus offers a practical solution for minimizing radioactive waste in PET/CT imaging.
  • Optimized scheduling is crucial for sustainable and cost-effective nuclear medicine practices.
  • This approach supports better patient care through efficient resource allocation.
