Gamma camera coincidence imaging with [18F]fluorodeoxyglucose in the pretreatment evaluation of patients with oesophageal cancer

Abstract

This study investigated the role of [18F]fluorodeoxyglucose (FDG) dual-head gamma camera coincidence imaging (GCI) in the pretreatment evaluation of patients with oesophageal cancer. Twenty-two patients (20 men; mean age, 64 years) with untreated, biopsy proven squamous cell carcinoma of the oesophagus underwent positron emission tomography (PET) and GCI 1 and 3 h after a single injection of FDG, respectively. Computed tomography (CT) was performed within 2 weeks of the FDG imaging. The sensitivity of lesion detection was compared between GCI and PET. Regional (N) and distant (M) metastases detected by GCI were evaluated with reference to PET and CT. The staging obtained by each modality was also compared with pathological staging in nine patients who underwent surgery. FDG PET detected 22 primary tumours, 34 metastatic lymph nodes and four organ metastases. Of them, GCI detected all primary tumours, 24 (71%) metastatic lymph nodes, and none of the organ metastases. Lymph nodes missed by GCI were smaller in size and the majority of them were located in the thoracic region. GCI provided N and M staging identical to CT and PET in eight patients and improved staging over CT in four patients. On the other hand, GCI missed metastases detected by both PET and CT in five patients. The addition of GCI to CT could improve detection of patients with metastasis to 82% (18/22) compared with 64% (14/22) detected by CT alone. In patients with pathological staging (n = 9), GCI could influence management changes in two patients (22%). In conclusion, FDG GCI has a role that is complementary to CT in the initial staging of patients with oesophageal cancer, and due to the additional detection of nodal metastasis, GCI can provide staging information, which may influence changes in management.

Clinical utility of 2-[18F] fluoro-2-deoxy-D-glucose positron emission tomography in predicting World Health Organization grade in pancreatic neuroendocrine tumors

“…Whole-body FDG-PET was performed as described previously. 15,[18][19][20] Briefly, each patient fasted for $4 hours before intravenous administration of ;370 MBq FDG. Serum glucose levels were determined just before FDG injection; all enrolled patients were normoglycemic (serum glucose <150 mg/dL).…”

Correlation of GLUT-1 Overexpression, Tumor Size, and Depth of Invasion with 18F-2-fluoro-2-deoxy-d-glucose Uptake by Positron Emission Tomography in Colorectal Cancer

“…The intrinsic resolution was 3.7 mm full width at half maximum, and the sensitivity of the device was 7.3 cps/Bq cm −3 . The bladder was continuously flushed with 1000 mL of saline via a triple-lumen catheter [15,16].…”

Systemic control and evaluation of the response to neoadjuvant chemotherapy in resectable thoracic esophageal squamous cell carcinoma with 18F-fluorodeoxyglucose positron emission tomography-positive lymph nodes

“…PET imaging and the diagnosis of PET-positive LNs PET was performed using a dedicated PET scanner (HEADTOME/SET 2400W, Shimadzu Co., Kyoto, Japan) as reported previously [14,15]. Each patient fasted for at least 4 h before the intravenous administration of approximately 370 MBq of FDG.…”
