Single-photon emission computed tomography (SPECT) is a nuclear radiology study that measures the blood flow in the brain. A safe, short-lived radioactive substance is injected into the arm and a CT (computed tomography) scan is performed shortly afterwards.

Before your child’s epilepsy surgery, two SPECT scans will be needed: One, called an ictal (ICK-tull) scan, will be done while your child is having a seizure, and the other, called an interictal (IN-ter-ICK-tull) scan, will be done when your child is not having a seizure.

Jan 21, 2021 · The ictal and interictal perfusion images should be reviewed visually according to published guidelines [32, 33], and quantification techniques should be applied, such as using ROIs, comparison with a database of healthy subjects, and voxel-based analysis.

Ictal single photon emission computed tomography (SPECT) can be used as an advanced diagnostic modality to detect the seizure onset zone in the presurgical evaluation of people with epilepsy.

Jul 12, 2004 · The authors discuss the impact of ictal SPECT subtraction or difference imaging methods and the initial evidence for proof-of-principle that SPM can be used to provide objective, accurate analysis of ictal SPECT scans in patients with temporal and extratemporal lobe epilepsy.

The ictal SPECT scan shows a focal area of intense uptake in the right frontal lobe. Computed tomography (CT) and magnetic resonance imaging (MRI) studies carried out at our and other institutions were normal.

ISAS (Ictal-Interictal SPECT Analysis by SPM) is an objective tool for analyzing ictal vs. interictal SPECT scans. The goal of ictal SPECT is to localize the region of seizure onset for epilepsy surgery planning.

Interictal imaging takes place while seizure free. Images are taken with a large device called a SPECT Camera located in Nuclear Medicine. This camera is like a CT scanner. You lay down on a table and place your head into a head rest so you will lay still for the pictures. The SPECT Camera rotates around the head to take each picture.

A SPECT scan is a nuclear radiology study that measures the blood flow in the brain and helps us identify the region of the brain your seizures come from. HOW DOES IT WORK?

SPECT involves an intravenous injection of two substances, technetium and a blood flow agent. The injection is given during or immediately following a seizure (ictal SPECT). Technetium is a very low energy, radioactive substance that is used in nearly all nuclear medicine scans in infants, children and adults.
