Comparison of single photon emission computed tomography-computed tomography, computed tomography, single photon emission computed tomography and planar scintigraphy for characterization of isolated skull lesions seen on bone scintigraphy in cancer patients.

Purpose: The purpose of this study is to evaluate the added value of single photon emission computed tomography-computed tomography (SPECT-CT) over planar scintigraphy, SPECT and CT alone for characterization of isolated skull lesions in bone scintigraphy (BS) in cancer patients.

Materials And Methods: A total of 32 cancer patients (age: 39.5 ± 21.

Dual tracer functional imaging of gastroenteropancreatic neuroendocrine tumors using 68Ga-DOTA-NOC PET-CT and 18F-FDG PET-CT: competitive or complimentary?

Objective: This study aimed to compare the diagnostic performance of Ga-DOTANOC PET/CT with F-FDG PET/CT in the patients with gastroenteropancreatic neuroendocrine tumors (GEP-NETs).

Patients And Methods: Data of 51 patients with definite histological diagnosis of GEP-NET who underwent both Ga-DOTA-NOC PET-CT and F-FDG PET-CT within a span of 15 days were selected for this retrospective analysis. Sensitivity, specificity, and predictive values were calculated for Ga-DOTA-NOC PET-CT and F-FDG PET-CT, and results were compared both on patientwise and regionwise analysis.

68Ga-DOTANOC PET/CT for baseline evaluation of patients with head and neck paraganglioma.

Unlabelled: The purpose of this study was to evaluate the role of (68)Ga-labeled DOTANOC PET/CT for baseline evaluation of patients with head and neck paragangliomas (HNPs).

Methods: The data for 26 patients (mean age ± SD, 34.3 ± 10.

Can hybrid SPECT-CT overcome the limitations associated with poor imaging properties of 131I-MIBG?: Comparison with planar scintigraphy and SPECT in pheochromocytoma.

Objective: This study aimed to evaluate the incremental value of (131)I-MIBG hybrid SPECT-CT over planar scintigraphy (PS) and SPECT alone in patients with clinical or biochemical suspicion of pheochromocytoma.

Methods: A total of 126 adrenals of 63 patients (mean [SD] age, 28.6 [15.

Sister Mary Joseph nodule in endometrial carcinoma: detection with FDG PET/CT.

Sister Mary Joseph nodules are very rare. They are commonly caused by gastrointestinal tract and ovarian cancers, but they are seen rarely in uterine carcinoma, lung carcinoma, breast carcinoma, and others. We present F-FDG PET/CT findings in a 55-year-old woman with endometrial adenocarcinoma, who presented with a mass protruding from the umbilicus after surgery and pelvic radiotherapy.

Primary intracranial basaloid squamous cell carcinoma: an enigma.

Primary intracranial squamous cell carcinoma is extremely rare, with most cases arising from malignant transformation of dysembryogenetic lesions such as epidermoid and dermoid cysts. Intracranial squamous cell neoplasm arising de novo is even rarer and has been reported in only four patients to date. We herein describe a case of primary intracranial squamous cell carcinoma arising de novo in the right frontal lobe in a 35-year-old woman treated with a combination of surgery and postoperative conformal radiation.

68Ga-DOTA-NOC PET and peptide receptor radionuclide therapy in management of bilateral ovarian metastases from gastrointestinal carcinoid.

The management of neuroendocrine tumours is challenging when curative surgery is ruled out because of distant metastases. We report a case of gastrointestinal carcinoid with bilateral ovarian metastases in a 50-year-old female who received octreotide therapy followed by peptide receptor radionuclide therapy and surgery thereafter. Somatostatin receptor expression on neuroendocrine tumours has implications in diagnosis and therapy.

Hybrid SPECT-CT for characterizing isolated vertebral lesions observed by bone scintigraphy: comparison with planar scintigraphy, SPECT, and CT.

Purpose: We aimed to assess the role of single photon emission computed tomography-computed tomography (SPECT-CT) for characterizing isolated vertebral lesions observed by bone scintigraphy compared to planar scintigraphy, SPECT, and CT, and to evaluate the impact of SPECT-CT on patient management.

Materials And Methods: Data from 99 patients (mean age, 52.4±18.

18F-FDG PET-CT for detecting recurrent gastric adenocarcinoma: results from a Non-Oriental Asian population.

Objective: To evaluate the utility of fluorine-18 fluorodeoxyglucose (18F-FDG) PET-CT in the diagnosis of recurrent gastric adenocarcinoma in a Non-Oriental Asian population.

Methods: In this retrospective analysis, data from 72 Non-Oriental Asian patients, who underwent 93 18F-FDG PET-CT studies, were evaluated. All patients had histopathologically proven gastric adenocarcinoma, for which they had undergone primary treatment.

Postorchiectomy intrascrotal hematoma mimicking local recurrence on 18F-FDG PET/CT: a diagnostic dilemma.

Intratesticular hematomas usually develop immediately after orchiectomy is done for testicular tumors and may last for 3 to 6 weeks or longer. They may be confused with local recurrence on clinical examination and imaging. We present the (18)F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) images of a 30-year-old man who underwent right radical transinguinal orchiectomy for seminoma.

Imaging thrombus in cancer patients with FDG PET-CT.

The incidence of thrombosis in patients with underlying primary malignancy is high. The thrombus may be the more common venous thromboembolism (VTE) or the rare tumour thrombus. VTE is a common entity in cancer patients and is managed with anticoagulant therapy, while tumour thrombosis requires aggressive multimodality management.

Role of FDG-PET/CT in detection of recurrent disease in colorectal cancer.

Background: One-third of patients with colorectal cancer (CRC) are likely to have a recurrence within the first 1-2 years. Conventional imaging modalities have limitations in detecting recurrent disease early. The purpose of this study was to assess the usefulness of fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) in the detection of recurrence in patients with CRCs.
