The purpose was to compare contrast-enhanced PET/CT (cePET/CT) and non contrast-enhanced PET/MRI (PET/MRI) concerning diagnostic accuracy in evaluation of abdominal lesions. METHOD AND MATERIALS 21 patients (mean age 59.5 years, range 35 to 78 years, 11 female, 10 male) with suspected ...
Accuracy of CT Without Versus With Oral Contrast in the Diagnosis of Acute Appendicitis 来自 ResearchGate 喜欢 0 阅读量: 13 作者:R Tappouni,AR Mohamed,N Sarwani 摘要: Objectives. To compare the effectiveness of the bismuth breast shield and partial CT scan in reducing entrance skin dose and ...
Background and Objectives: Patients with acute ischemic stroke (AIS) treated with endovascular thrombectomy (EVT) in the late window (6-24 hours) can be evaluated with CT perfusion (CTP) or with noncontrast CT (NCCT) only. Whether outcomes differ depending on the type of imaging selection is...
Advances in CT technology, such as Dual Energy CT (DECT), allows for qualitative and quantitative reconstructions during post-processing enabling fat percentage quantification from acquisitions with and without contrast enhancement [10,11]. We hypothesized that DECT can diagnose moderate-severe liver stea...

Imaging guidance for COVID-19 advises single-phase CT with no contrast enhancement or post-contrast series, as radiological features of COVID-19 tend to be confined to the lungs, without involvement of the pleura or mediastinum6. Direct post-contrast arterial-phase CT is recommended in the cont...
77%–88% sensitivity, 50%–71% specificity, and 71%–74% accuracy were obtained in the group without positive intraduodenal contrast, versus 50%–80% sensitivity, 57%–71% specificity, and 59%–71% accuracy in the group with positive intraduodenal contrast. With the exception of the ...
The CT scan without contrast was performed immediately prior to the PET scan with a multi-detector 2-slice spiral CT scanner. For the whole-body emission scan, 9-bed positions were examined at 3 min per step. CT and PET images were reconstructed onto a 512 × 512 matrix and a 128 × ...
In contrast, ctDNA-positive patients who were treated with ACT had a significantly improved RFS than ctDNA-positive patients without ACT (p < 0.05). Similar results were observed when analyzed in AD and SqCC datasets separately (Supplementary Fig. 8). Therefore, postsurgical ctDNA status ...
