pydicom is a pure Python library for reading, modifying, and writing DICOM medical imaging files and File-sets in a pythonic way. It optionally converts compressed and uncompressed Pixel Data to NumPy ndarrays and back.

Use cases

• read and parse DICOM files in python
• modify DICOM metadata like patient name and save the file
• convert DICOM pixel data to a numpy array
• work with DICOMDIR and DICOM File-sets
• extract medical imaging data for machine learning pipelines
• write DICOM datasets from scratch in python

When to choose

• you need general-purpose DICOM dataset I/O in Python without heavy dependencies
• you want to inspect or edit DICOM tags and metadata programmatically
• you need pixel data as NumPy arrays for analysis or ML
• you want a pure Python library that runs anywhere Python runs

When to avoid

• you need DICOM networking or SOP class services (use pynetdicom instead)
• you need turnkey anonymization workflows (use deid instead)
• you need a full medical imaging viewer or PACS application
