Get your CT 4D Parathyroid Scan at Molecular Diagnostics and Therapy, an NABL & NABH Accredited Diagnostic Centre, for detailed localization and evaluation of abnormal parathyroid glands. 4D CT uses high-resolution CT imaging along with contrast enhancement over multiple phases to assess the size, location, blood supply, and enhancement pattern of parathyroid lesions. With advanced CT technology and experienced radiology specialists, we provide accurate imaging and reliable reporting to support diagnosis and surgical planning.
About CT 4D Parathyroid
The CT 4D Parathyroid Scan is a specialized imaging examination commonly used when a parathyroid gland is suspected to be overactive or when its exact location needs to be identified before surgery. It provides detailed anatomical information about the neck and upper chest and can help detect parathyroid glands that are enlarged or located in an unusual position. This examination may be particularly useful when other localization studies do not provide sufficient information or when detailed pre-operative mapping is required.
What is a CT 4D Parathyroid Scan?
4D CT Parathyroid is a contrast-enhanced CT examination that captures images during different phases after contrast administration. The additional "dimension" refers to changes in contrast enhancement over time. These images allow the radiologist to assess the appearance and enhancement pattern of suspected parathyroid tissue and distinguish it from nearby thyroid tissue, lymph nodes, and other neck structures.
Common Reasons for CT 4D Parathyroid
Localization of suspected abnormal parathyroid glands
Evaluation of primary hyperparathyroidism
Pre-operative localization before parathyroid surgery
Assessment when ultrasound or other imaging is inconclusive
Evaluation of ectopic or unusually positioned parathyroid glands
Assessment of persistent or recurrent hyperparathyroidism
Identification of multiple abnormal parathyroid glands
Detailed anatomical mapping for surgical planning
Conditions Evaluated
Hyperparathyroidism
The scan can help localize an abnormal parathyroid gland in patients with laboratory findings suggestive of hyperparathyroidism.
Parathyroid Adenoma
A parathyroid adenoma is a common cause of primary hyperparathyroidism. 4D CT can help identify its location and characterize its relationship with surrounding structures.
Ectopic Parathyroid Gland
Some parathyroid glands may be located outside their usual anatomical position. 4D CT can help identify ectopic glands in the neck or upper chest.
Persistent or Recurrent Hyperparathyroidism
In selected patients who have persistent or recurrent disease after previous surgery, 4D CT may assist in locating residual or additional abnormal parathyroid tissue.
Multiple-Gland Disease
Detailed imaging can help identify more than one enlarged or abnormal parathyroid gland when clinically suspected.
Who Should Consider This Scan?
Your doctor may recommend a CT 4D Parathyroid Scan if you:
Have laboratory findings suggesting hyperparathyroidism
Have elevated parathyroid hormone or calcium levels
Are being evaluated for parathyroid surgery
Have an abnormal parathyroid gland suspected on previous imaging
Have inconclusive ultrasound or other localization studies
Have persistent or recurrent hyperparathyroidism after surgery
Require evaluation for an ectopic parathyroid gland

Test information: Fasting NOT needed
Reporting: Within 24 hours*
Fasting may be required depending on the CT protocol followed by the diagnostic centre. Follow the instructions provided before the examination.
Inform the radiology team about any previous allergy or reaction to iodinated contrast material.
Inform your doctor or radiology team if you have kidney disease, thyroid disease, or other significant medical conditions.
Tell the team about all medicines and supplements you are currently taking, especially if you have been advised to follow any specific medication instructions before the scan.
Inform the radiology team if you are pregnant or think you may be pregnant.
Remove necklaces, chains, earrings, or other metal objects around the neck before the examination.
Bring previous ultrasound, nuclear medicine scans, CT/MRI reports, and relevant blood test results such as calcium or parathyroid hormone reports, if available.
Follow any additional instructions regarding contrast administration, hydration, or medication provided by your doctor or the diagnostic centre.
CT प्रोटोकॉल के अनुसार जांच से पहले उपवास की आवश्यकता हो सकती है। जांच से पहले डायग्नोस्टिक सेंटर द्वारा दिए गए निर्देशों का पालन करें।
यदि आयोडीनयुक्त कॉन्ट्रास्ट से पहले कभी एलर्जी या किसी प्रकार की प्रतिक्रिया हुई हो, तो रेडियोलॉजी टीम को अवश्य बताएं।
यदि आपको किडनी की बीमारी, थायरॉइड से संबंधित समस्या या कोई अन्य महत्वपूर्ण मेडिकल स्थिति है, तो डॉक्टर या रेडियोलॉजी टीम को सूचित करें।
वर्तमान में ली जा रही सभी दवाओं और सप्लीमेंट्स के बारे में टीम को बताएं, विशेषकर यदि जांच से पहले किसी दवा के संबंध में विशेष निर्देश दिए गए हों।
यदि आप गर्भवती हैं या गर्भावस्था की संभावना है, तो जांच से पहले रेडियोलॉजी टीम को सूचित करें।
जांच से पहले गर्दन के आसपास पहनी हुई चेन, नेकलेस, कान की बालियाँ या अन्य धातु की वस्तुएँ हटा दें।
यदि उपलब्ध हों, तो पिछली अल्ट्रासाउंड, न्यूक्लियर मेडिसिन स्कैन, CT/MRI रिपोर्ट तथा कैल्शियम या पैराथायरॉइड हार्मोन से संबंधित रक्त जांच रिपोर्ट साथ लेकर आएं।
कॉन्ट्रास्ट, पानी पीने या दवाओं से संबंधित डॉक्टर या डायग्नोस्टिक सेंटर के अतिरिक्त निर्देशों का पालन करें।
