The Single-Photon Emission Computed Tomography (SPECT
) market is expected to witness tremendous growth owing to the new 99mtc labelled agents for visualizing biologically significant events, and integration of X-ray tomography (CT) In SPECT
gunlerde yapilmis olup daha erken goruntuleme yapilan Hassan ve ark.'nin (13) calismasinda SPECT
'BT nin klinik katkisinin %14 gibi nispeten dusuk raporlanmasinin goruntuleme suresinden kaynaklanabilecegi dusunulmustur.
"This is a seminal year for us and we have two big opportunities in front of us, in SPECT
and the D3S and over the next 10 years both are multimillion dollar markets - so we have a strong position in a large global market.
Goruntuleme ve Kantitatif Degerlendirme
The reader's average score [1-5] for detectability, lesion location and lesion size, and confidence that the lesion was malignant averaged 4.6 for the PET readers and 4.5 for the SPECT
1) In the qualitative analysis, when an increased activity involvement was determined in one or more areas of the lung, the SPECT
was accepted as positive.
Higher temporal resolution of SPECT
should result in more accurate determination of end-systolic and end-diastolic frames and hence more accurate assessment of ventricular volumes.
The processed images were displayed and analyzed by using Corridor 4DM (Segami) v5.1, Cedars-Sinai quantitative perfusion SPECT
(QPS4) and quantitative gated SPECT
[sup.99m]Tc-sestamibi and [sup.123]I SPECT
images (with attenuation correction) were anonymized and reconstructed on the Siemens Syngo workstation using the FLASH 3D-algorithm (eight iterations, eight subsets, Gaussian 9.00 filter).
Hybrid systems integrating SPECT
with a conventional CT allow a fairly exact overlay of molecular and morphological information and are more accurate for diagnosis and staging than WBS alone [9, 10].
Single photon emission computed tomography (SPECT
) with [sup.99m]Tc-ethyl cysteine dimer ([sup.99m]Tc-ECD) has been widely used to evaluate many types of cerebrovascular diseases and brain disorders by measuring regional cerebral blood flow (rCBF) [1-6].
