Parathyroid Sestamibi Scan Report

Procedure: [Parathyroid scintigraphy with Tc-99m sestamibi; technique: [Planar / SPECT / SPECT/CT]; protocol: [single-phase / dual-phase]]

Date: [Study date]

Referring Physician: [Name, credentials]

Interpreting Physician: [Name, credentials]

Clinical Information

Indication: [Clinical problem and question to be answered] (If not provided, state "not provided.")

Type of hyperparathyroidism: [primary / secondary / tertiary / not provided]

• Pertinent history: [Relevant history including MEN syndromes, nephrolithiasis, bone disease, symptoms] (If not provided, state "not provided.")
• Prior neck surgery: [Yes (details) / No / not provided]
• Prior localization studies: [Modality, date, and key results] (If none, state "No prior imaging available for comparison.")
• Serum PTH: [value, units, date] (If not provided, state "not provided.")
• Serum calcium: [value, units, date] (If not provided, state "not provided.")

Technique

• Radiotracer: Tc-99m sestamibi, [activity] mCi ([activity] MBq), administered IV.
• Protocol: [dual-phase / single-phase]
• Acquisitions: [Planar projections and/or SPECT/CT of neck and mediastinum as performed]
• Timing: Early images at [XX] minutes; delayed images at [XX] minutes post-injection (Include only phases performed.)
• CT details: [low-dose for attenuation correction/localization / diagnostic-quality] (Include only if SPECT/CT performed.)
• Anatomic coverage: [Superior to inferior extent of imaging]
• Image quality: [adequate / limited by motion / high thyroid retention / other limitations] (Only include limitations that affect interpretation.)

Findings

(List suspected hyperfunctioning foci in order of confidence using quadrant-based surgical localization, depth/compartment, anatomic landmarks, temporal uptake behavior, and SPECT/CT correlation.)

• Focus [#]: [Right / Left] [superior / inferior] parathyroid region.
  • Localization: [Depth relative to thyroid; compartment; relation to thyroid poles and other landmarks]
  • Temporal behavior: [Early uptake with delayed persistence / early uptake with washout / delayed-only focus]
  • SPECT/CT correlate: [Nodule size and characteristics if visible] (Include only if present.)
  • Confidence: [definite / probable / equivocal] — [brief rationale]
• Focus [#]: (Repeat structure for additional foci as needed.)

Pattern assessment: [Findings most consistent with single-gland disease / possible multi-gland disease / nonlocalizing] (Comment on ectopic locations if present.)

Negative/nonlocalizing study: No focal abnormal sestamibi retention to localize hyperfunctioning parathyroid tissue. [Relevant limitations.] (Use if applicable.)

Incidental findings: [Actionable or operatively relevant findings] (Include only if present; note CT limitations when appropriate.)

Impression

1. [Number] suspected focus/foci of hyperfunctioning parathyroid tissue: [laterality, quadrant, key anatomic relationship, size if available], confidence: [definite / probable / equivocal].
2. [If multiple foci:] Findings [suggest single-gland disease / raise concern for multi-gland disease].
3. [If nonlocalizing:] No focal abnormal sestamibi retention to localize hyperfunctioning parathyroid tissue; [primary limitation].
4. [Recommendation if likely to change management, e.g., correlate with ultrasound, consider 4D-CT or choline PET] (Include only if appropriate.)

(Avoid "parathyroid adenoma" unless histology is known; use "hyperfunctioning parathyroid tissue.")
