Molecular Imaging

The Only Cloud-based PACS for Molecular Imaging


Key Features

Molecular Imaging (MI) enables the visualization, characterization, and quantification of biologic processes taking place at the cellular and subcellular levels in patients. It is used to study the processes of how molecular abnormalities, found in cells, build up to form the basis of disease. It facilitates 1) early detection of disease 2) optimizing therapies that aim for certain molecular targets 3) predicting and monitoring response to therapy and 4) monitoring for disease recurrence.


In contrast to traditional radiological imaging that details end-stage gross pathology/anatomy, MI reveals, within a living subject, the underlying biology occurring deep within cells anywhere in the body, which helps physicians to better understand disease and gives them the ability to intervene with treatment at an earlier time.

Special Challenges of Molecular Imaging for PACS

Molecular images acquired by the scanners (i.e., raw data) are formed by collecting radiation emitted from a patient's body. The radiation activities are resulted from radioactive isotopes injected into patients. Due to the low doses of radioactive isotopes used, activity counts are relatively low, and thus images formed have little diagnostic value. In order to make use of the information collected, raw data need to be processed and quantified. The quantified results then will be used to evaluate the function of the human body. Such process does not exist in general radiology modalities, such as CT, MR, X-Ray, etc.


The following are unique for molecular imaging:

  • Multiple image types: Molecular imaging has 7 images types, while general radiology only has 1 type. Most PACS cannot store these images correctly.
  • Dynamic images: Dynamic images are required in order to accurately characterize human body's functions. 
  • ColorMolecular images are often presented in color. 
  • 3D Volumetric Imaging: SPECT and PET images are volumetric and they must be presented in three-dimensional volumetric views, allowing images to be extracted from any plane within the 3D volume on demand. 
  • Triangulation: In molecular imaging, the ability to triangulating between images from the three orthogonal planes is essential in order to accurately localize lesions. 
  • Real-Time Fusion: The functional SPECT and PET images are often fused with the corresponding anatomical CT or MR images on the fly, enabling precise localization of lesions in the body.
  • On-the-Fly Analysis: The functional SPECT and PET images, along with the anatomical CT and MR images,  are analyzed in real time to evaluate the disease.
  • Comparative Imaging: It’s crucial to be able to easily compare multiple prior and current exams to effectively monitor the progress of disease.


Most conventional PACS cannot support the above features.

PACSCloud – The One and Only PACS Solution for Molecular Imaging

PACSCloud is the one and only PACS that was built from ground up to handle molecular imaging natively at all levels, from interfacing with the scanners, processing tools for technologists, to diagnostics tools to physicians. 


PACSCloud can interface with any molecular imaging scanners still in use today, regardless of their make, model, age, and even if they are not capable of supporting DICOM communication protocol.


Besides the comprehensive processing tools for general nuclear medicine, and advanced fusion tools for PET-CT, SPECT-CT and PET-MR, it provides AI-powered diagnostic analytics for cardiac and brain diseases.


In comparison, most conventional PACS depend on screen captures to view molecular images.
