Ultrasound and Nuclear Medicine Records
How do I make sure I get the complete record from my ultrasound or PET scan?
Specifically ask for all still images and cine loops (video clips) for ultrasounds, and all time-point images with fused PET/CT data for nuclear medicine studies. Providers often leave out video files and multi-phase data unless you explicitly request them.
While CT, MRI, and X-rays create images based on the structure of your body, Ultrasound and Nuclear Medicine provide a different kind of information. Ultrasound uses sound waves to create real-time images, while Nuclear Medicine uses radioactive tracers to visualize organ function. These records have unique characteristics and access challenges.
Ultrasound Records: Capturing Motion
Ultrasound, also called sonography, uses high-frequency sound waves to create images of organs and structures inside the body. It is widely used in obstetrics, cardiology, and for guiding procedures like biopsies.
Key Characteristics of Ultrasound Records
Real-Time Video
A key feature of ultrasound is its ability to show movement, such as a beating heart or blood flowing through a vessel. A complete ultrasound record may include not just still images but also short video clips called "cine loops."
Operator Dependent
The quality of an ultrasound is highly dependent on the skill of the sonographer performing the exam. They must know how to position the probe to get the correct views.
Still Images and Measurements
In addition to videos, the sonographer will capture many still images and take precise measurements of various structures.
Common Failures in Ultrasound Records
- • Missing Cine Loops: Often, when you receive a copy of your ultrasound, you get only the still images and not the video clips, which can be critical for diagnosis.
- • Incomplete Views: If the sonographer did not capture all the required views, the study may be considered incomplete or non-diagnostic.
Nuclear Medicine Records: Visualizing Function
Nuclear Medicine is a branch of radiology that uses small amounts of radioactive material (radiotracers) to diagnose and treat disease. These tracers are injected, swallowed, or inhaled, and they accumulate in the organ or area being examined. A special camera then detects the radiation and creates images.
Key Characteristics of Nuclear Medicine Records
Functional Information
Unlike most other imaging which shows anatomy, Nuclear Medicine shows physiology. For example, a cardiac stress test shows how well blood is flowing to the heart muscle.
Multiple Time Points
Many nuclear medicine studies involve taking images at multiple time points (e.g., immediately after injection and then again several hours later) to see how the tracer is processed by the body.
Hybrid Imaging (PET/CT)
It is now common to combine nuclear medicine with CT in a single scanner (e.g., a PET/CT). This allows the functional information from the PET scan to be overlaid on the anatomical map from the CT scan.
Common Failures in Nuclear Medicine Records
- • Missing Time Points: You may receive the images from only one time point, not the complete series.
- • Incorrect Tracer Information: The report should specify the exact radiotracer used and the dose. This information is sometimes omitted.
- • Separated Hybrid Scans: For a PET/CT, you should receive both the PET and CT data, correctly fused together. Sometimes, you may receive only one part of the study.
Accessing These Specialized Records
The process for requesting ultrasound and nuclear medicine records is the same as for other imaging. However, due to their unique characteristics, it is especially important to be specific in your request.
| Study Type | What to Request |
|---|---|
| Ultrasound | "All still images and cine loops (video clips)" |
| Nuclear Medicine | "All imaging from all time points" |
| PET/CT | "Both PET and CT data, fused images" |
| Cardiac Stress Test | "Rest and stress images, complete report" |
Be Specific in Your Request
Because these specialized records often include video files and multiple acquisition time points, the person fulfilling your request may not include everything unless you specifically ask. When in doubt, request "the complete study including all images, video clips, and all time points."

Frequently Asked Questions
What should I request when asking for a complete copy of my ultrasound?
Specifically request both the still images and the cine loops (video clips) from your ultrasound. Many facilities only provide static still images by default and omit the dynamic video sequences, which can contain clinically important information about organ motion, blood flow, or cardiac function that is not visible in a single frame.
What type of records are generated from a PET scan?
A PET/CT scan generates both PET data (showing metabolic activity) and CT data (showing anatomy), which are then fused together. When requesting your PET/CT records, ask for all components: the fused PET/CT images, the standalone PET images, the standalone CT images, and the written radiology report. Each component may be on a separate disc or in separate folders.
How are nuclear medicine records different from other imaging?
Nuclear medicine studies like SPECT scans, thyroid scans, and bone scans involve radioactive tracers and generate both images and functional data that is different from anatomic imaging. The records include images acquired at multiple time points and the written interpretation. Always request the complete multi-phase dataset, not just a single time point.
Do I need prior authorization for an ultrasound?
Requirements vary by insurer and the type of ultrasound. Routine screening ultrasounds such as pregnancy ultrasounds and abdominal screenings often do not require prior authorization. More specialized ultrasounds such as cardiac stress echocardiograms or vascular Doppler studies may require prior authorization under some insurance plans. Check with your insurer before the study.
