PURPOSE: Severity of abdominal obesity and possibly levels of metabolic activity of abdominal visceral adipose tissue (VAT) are associated with an increased risk for cardiovascular disease (CVD). In this context, the purpose of the current study was to evaluate the reproducibility and repeatability of a semi-automated method for assessment of the metabolic activity of VAT using 2-deoxy-2-[18 F]fluoro-D-glucose ([18 F]FDG) positron emission tomography (PET)/x-ray computed tomography (CT)...

Although lung cancer has a high propensity for distant metastatic disease, penile metastases from primary lung neoplasms are considered particularly rare. A 71-year-old male presented to our hospital with a rapidly enlarging hard palpable penile mass. MR imaging demonstrated two penile masses centered in the left and right corpus cavernosa. Subsequent CT imaging revealed a spiculated pulmonary mass in the right upper lobe with PET/CT, MRI, and surgical exploration, demonstrating evidence of metastases to the left adrenal gland, right subscapularis muscle, brain, and small bowel...

BACKGROUND: In case of suspicious lymph nodes on computed tomography (CT) or fluorodeoxyglucose positron emission tomography (FDG-PET), advanced tumour size or central tumour location in patients with suspected non-small cell lung cancer (NSCLC), Dutch and European guidelines recommend mediastinal staging by endosonography (endobronchial ultrasound (EBUS) and endoscopic ultrasound (EUS)) with sampling of mediastinal lymph nodes. If biopsy results from endosonography turn out negative, additional surgical staging of the mediastinum by mediastinoscopy is advised to prevent unnecessary lung resection due to false negative endosonography findings...

An 89-year-old woman presented with seizure and hyponatremia. CT and MRI demonstrated mass-like enlargement of the adrenal glands and multiple pulmonary nodules. PET/CT performed to evaluate for metastatic disease demonstrated intense 18F-FDG uptake within enlarged adrenal glands. Given mild uptake in the pulmonary nodules, the differential diagnosis for the adrenal uptake included lymphoma, granulomatous infection, and less likely, metastatic lung cancer.

We measured the repeatability of FDG PET/CT uptake metrics when acquiring scans in free breathing (FB) conditions compared with deep inspiration breath hold (DIBH) for locally advanced lung cancer. Twenty patients were enrolled in this prospective study. Two FDG PET/CT scans per patient were conducted few days apart and in two breathing conditions (FB and DIBH). This resulted in four scans per patient. Up to four FDG PET avid lesions per patient were contoured. The following FDG metrics were measured in all lesions and in all four scans: Standardized uptake value (SUV)peak , SUVmax , SUVmean , metabolic tumor volume (MTV) and total lesion glycolysis (TLG), based on an isocontur of 50% of SUVmax ...

Quantitative analysis of glucose consumption measured by maximum standardized uptake value (SUVmax) in lung adenocarcinoma (LA) remains in discussion and metabolic information provided by FDG-PET is not included in cancer staging. The first aim of this work was to evaluate the correlation between SUVmax and different histologic subtypes of LA. The second aim was to establish the correlation between SUVmax and TNM, genetic mutations and prognostic. Glucose consumption of primary tumor was quantified using SUVmax in 112 patients with histologically-confirmed LA...

A 49-year-old man was admitted to our hospital for an abnormal chest shadow. Computed tomography showed a pulmonary nodular shadow in the right upper lobe and swelling of the right hilar, mediastinal and supraclavicular lymph nodes. A positron emission tomography(PET) scan showed fluorodeoxyglucose accumulation in the tumor and swollen lymph nodes. He was diagnosed with stage cT1aN3M0 (ⅢB) pulmonary adenocarcinoma and was treated with a combination of cisplatin and paclitaxel. After 6 cycles of chemotherapy, serum carcinoembryonic antigen (CEA) level was markedly decreased...

INTRODUCTION: Several clinical guidelines indicate that brain metastasis screening (BMS) should be guided by disease stage in non-small cell lung cancer (NSCLC). We estimate that screening is performed more broadly in practice, and patients undergo brain imaging at considerable cost with questionable benefit. Our aim was to quantify the use and detection rate of BMS in a contemporary cohort staged with 18 F-fluorodeoxyglucose positron emission tomography/computed tomography (PET-CT). METHODS: We conducted a retrospective review of prospectively collected data from three major lung cancer referral centres in Brisbane between January 2011 and December 2015...

BACKGROUND: Several studies have shown the advantage of delayed-time-point imaging with 18F-FDG-PET/CT to distinguish malignant from benign uptake. This may be relevant in cancer diseases with low metabolism, such as breast cancer. We aimed at examining the change in SUV from 1 h (1h) to 3 h (3h) time-point imaging in local and distant lesions in patients with recurrent breast cancer. Furthermore, we investigated the effect of partial volume correction in the different types of metastases, using semi-automatic quantitative software (ROVER™)...

Objective. 99m Tc-ethylenedicysteine-glucosamine (99m Tc-EC-G) was developed as a potential alternative to 18 F-FDG for cancer imaging. A Phase 2 study was conducted to compare 18 F-FDG PET/CT and 99m Tc-EC-G SPECT/CT in the detection and staging of patients with non-small cell lung cancer (NSCLC). This study was aimed to demonstrate that 99m Tc-EC-G SPECT/CT was not inferior to 18 F-FDG PET/CT in patients with confirmed NSCLC. Methods. Seventeen patients with biopsy proven NSCLC were imaged with 99m Tc-EC-G and 18 F-FDG to detect and stage their cancers...

With targeted treatments playing an increasing role in oncology, the need arises for fast non-invasive genotyping in clinical practice. Radiogenomics is a rapidly evolving field of research aimed at identifying imaging biomarkers useful for non-invasive genotyping. Radiogenomic genotyping has the advantage that it can capture tumor heterogeneity, can be performed repeatedly for treatment monitoring, and can be performed in malignancies for which biopsy is not available. In this systematic review of 187 included articles, we compiled a database of radiogenomic associations and unraveled networks of imaging groups and gene pathways oncology-wide...

INTRODUCTION: Advanced imaging can inform prognosis and may be a mechanism to de-escalate unnecessary end-of-life care in patients with cancer. Associations between greater use of advanced imaging and less-aggressive end-of-life care in real-world practice has not been examined. METHODS: We conducted a retrospective analysis of SEER-Medicare data on patients who died from breast, lung, colorectal, or prostate cancer between 2002 and 2007. Hospital referral region (HRR)-level use of computerized tomography (CT), magnetic resonance imaging, and positron emission tomography was categorized by tertile of imaging use and correlated with hospice enrollment overall and late hospice enrollment using multivariable logistic regression...

BACKGROUND: Positron Emission Tomography/computed tomography (PET/CT) is an imaging technique which has a role in the detection and staging malignancies (both in first diagnosis and follow-up). The finding of an unexpected region of FDG (Fluorodeoxyglucose) uptake can occur when performing whole-body FDG-PET, raising the possibility of a second primary tumor. The aim of this study was to evaluate our experience of second primary cancer incidentally discovered during PET/CT examination performed for pancreatic diseases, during the initial work-up or follow-up after surgical resection...

Muscle-invasive bladder cancer (MIBC) has a tendency toward urothelial multifocality and is at risk for local and distant spread, most commonly to the lymph nodes, bone, lung, liver, and peritoneum. Pretreatment staging of MIBC should include imaging of the urothelial upper tract for synchronous lesions; imaging of the chest, abdomen, and pelvis for metastases; and MRI pelvis for local staging. CT abdomen and pelvis without and with contrast (CT urogram) is recommended to assess the urothelium and abdominopelvic organs...
