1. Indications

The digitization of glass microscope slides for examination and selection of retrieved archival tissues is indicated in various scenarios where molecular analysis is required. The following conditions may warrant this procedure:

• Archival Tissue Retrieval This procedure is performed when previously diagnosed tissue samples need to be re-evaluated for further analysis, particularly in cases where molecular testing, such as KRAS mutational analysis, is necessary.
• Remote Pathology Consultation Digitization allows for remote pathologists to examine slides, which is beneficial in situations where expert consultation is required but not readily available on-site.
• Enhanced Diagnostic Accuracy The use of digital images can improve diagnostic accuracy by allowing for the application of computer algorithms that assist in the pathologic diagnosis.

2. Procedure

The procedure for digitizing glass microscope slides involves several key steps that ensure the accurate conversion of physical slides into a digital format. Each step is crucial for maintaining the integrity of the tissue samples and the quality of the digital images.

• Step 1: Preparation of Slides Initially, the glass microscope slides containing the archival tissue samples are prepared for digitization. This may involve cleaning the slides to remove any contaminants that could affect the imaging quality.
• Step 2: Scanning Process The prepared slides are then placed into a specialized digital scanner designed for high-resolution imaging. The scanner captures detailed images of the slides, converting them into a digital format that can be stored and analyzed.
• Step 3: Image Storage Once the scanning is complete, the digital images are stored on a local computer server or within a cloud-based archive. This storage solution allows for easy access and management of the images for future analysis.
• Step 4: Remote Examination After digitization, the images can be accessed by remote pathologists who can conduct examinations without needing the physical slides. This step enhances collaboration and consultation among healthcare professionals.
• Step 5: Molecular Analysis Preparation Finally, the digitized images are prepared for molecular analysis, such as KRAS mutational analysis, ensuring that the necessary information is available for further diagnostic evaluation.

3. Post-Procedure

Post-procedure care following the digitization of glass microscope slides primarily involves the management and interpretation of the digital images. Once the slides have been digitized and stored, healthcare professionals can access the images for further analysis as needed. It is essential to ensure that the digital storage system is secure and that the images are backed up to prevent data loss. Additionally, any findings from the molecular analysis should be documented and communicated to the relevant healthcare providers for appropriate patient management. There are no specific recovery considerations for the procedure itself, as it is a non-invasive process that does not involve patient interaction.
