Oncology - General Nuclear Medicine Studies




The written report is the final product of the Nuclear Medicine consultation. Reports must contain specific information to identify the patient, the specific procedure, indications for the examination, radiopharmaceutical used and activity administered, route of administration, interval between tracer administration and imaging, succinct technical information about data acquisition and processing (especially the use and dose of additional drugs such as adenosine, CCK, morphine, lasix, etc), specific image and data analysis findings, and a conclusion.

The report should be concise, clear and specific. Standard anatomic designations and physiologic descriptors should be used. Jargon terms, such as "defect" or "photopenia", should not appear in the report. When possible, lesions should be specifically enumerated, physical size measured, and uptake quantified. When lesions are very numerous, the major areas of involvement should be specifically identified. When previous examinations are available, the improvement, progression or stability of disease should be identified. Examples of specific reports are contained with a description of each of the imaging procedures.


The following elements should be included in all reports:

Patient identifier: Name, gender, birth date, medical record number 

Date procedure started and date reported

Procedure Title

Indication: Brief statement of clinical problem and question to be answered

Technical factors: Radiopharmaceutical, dose, route of administration, type of scan, interval between injection and imaging, interventions

Reference to prior examination of the same type

Reference to other procedures

Findings: Address clinical question first.

Interpretation: As definitive as possible and avoid repetition of findings.



Clinical Statement: A 4 year old boy with neuroblastoma and an abdominal mass, for staging.

Radiopharmaceutical: 123I-MIBG 6 mCi i.v.

Comparison: [No prior 123I-MIBG studies for comparison]

Correlation: [None]

Technique: Following preparation with SSKI, the tracer was administered intravenously. Whole body, spot views and SPECT/CT images were recorded at 24 hours.


Head and Neck: [Physiologic 123I-MIBG concentration in the nose and salivary glands]

Chest: [Physiologic 123I-MIBG concentration in the myocardium]

Abdomen and Pelvis: [Focal 123I-MIBG concentration is seen in the 4 cm left adrenal mass, with additional focal activity in segment IV of the liver and in multiple thoracic and lumbar vertebrae.]

Extremities: [Multiple sites of focal 123I-MIBG activity are seen in the humeri and femora bilaterally].

Impression: [Multiple sites of 123I-MIBG avid disease]



Clinical Statement: Carcinoid tumor of the lung with multiple episodes of flushing.

Comparison [none]

Correlation: CT scan performed [date], which demonstrated 3X4 cm mass in the left lung, and 3 focal liver lesions.

Radiopharmaceutical: [6] mCi 111In- Pentetreotide intravenously.

Technique: Following intravenous injection, planar and SPECT/CT images were recorded at 4 and 24 hours.

Findings: A focus of uptake in the left lung and at three sites in the liver in segments [X,Y,Z] correlate with the lesions seen on CT.

Physiologic uptake is seen in the spleen and kidneys.

Impression: Somatostatin receptor expression in the known lung primary and liver metastases. No other lesions seen.
