Many studies demonstrate a high accuracy for PET in staging lymphoma, but few assess observer variation. This study quantified agreement for staging lymphoma with PET/CT. Methods: The PET/CT images of 100 patients with lymphoma who had been referred for staging were reviewed by 3 experienced observers, with 2 observers reviewing each series a second time. Ann Arbor stage and individual nodal and extranodal regions were assessed. Weighted κ (κw) and intraclass correlation coefficient were used…

Computed Tomography Observer Agreement in Staging Malignant Lymphoma

Computed tomography observer agreement in staging malignant lymphoma appears to be suboptimal, except for infraclavicular nodes.

Intra- and inter-observer agreement in the visual interpretation of interim 18F-FDG PET/CT in malignant lymphoma: influence of clinical information

The intra- and inter-observer agreements in evaluating interim PET/CT were relatively low for extranodal lesions, but they were substantial to almost perfect when interpreting nodal regions in malignant lymphoma, irrespective of the provision of clinical information.

Current status of FDG-PET/CT in staging of adult lymphoma

The updated guidance on the evaluation, staging and response assessment of patients affected by HL and NHL and on the use of PET/CT for staging and Response assessment suggest that a reasonable approach would be omit the standard full dose contrast-enhanced CT if not already performed, and perform a low-dose non-enhancing PET/ CT as a single imaging modality.

The iPET interpretation assured low interobserver variability and high sensitivity for identification of pHL patients suffering relapse is achieved if [18F]-fluorodeoxyglucose uptake above the MBPS value is rated as a PET-positive finding.

Inter-observer agreement improves with PERCIST 1.0 as opposed to qualitative evaluation in non-small cell lung cancer patients evaluated with F-18-FDG PET/CT early in the course of chemo-radiotherapy

PerCIST 1.0 provides a higher overall agreement between observers than the qualitative approach in categorizing early treatment response in NSCLC patients, and the inter-observer agreement is in fact strong when using PERCIST 2.0.

18F-FDG PET/CT Uptake Classification in Lymphoma and Lung Cancer by Using Deep Convolutional Neural Networks.

The fully automated anatomic localization and classification of fluorine 18-fluorodeoxyglucose PET uptake patterns in foci suspicious and nonsuspicious for cancer in patients with lung cancer and lymphoma by using a convolutional neural network is feasible and achieves high diagnostic performance when both CT and PET images are used.

High FDG activity in focal fat necrosis: a pitfall in interpretation of posttreatment PET/CT in patients with non-Hodgkin lymphoma

Identification of fat necrosis in patients with a solitary FDG-avid nodule after therapy is important and may lead to the avoidance of unnecessary interventions or treatment, whilst follow-up imaging can be helpful as the metabolic abnormality regresses with time.



Observer variation in FDG PET-CT for staging of non-small-cell lung carcinoma

Amongst experienced reporters in a single centre, there was a very high level of agreement for both mediastinal nodal stage and detection of distant metastases with PET-CT, which supports the use ofPET-CT as a robust imaging modality for staging NSCLC.

FDG PET in lymphoma: The need for standardization of interpretation. An observer variation study

There are substantial disparities among nuclear medicine physicians' interpretations of FDG PET scans of lymphoma patients, which may affect patient care and results of multi-institutional clinical trials.

Interobserver variability in the detection of cervical-thoracic Hodgkin's disease by computed tomography.

There are disparities among radiologists' interpretations of cervical-thoracic CT imaging of patients with Hodgkin's disease and it is proposed that a standardized method of reporting might improve the consistency of interpretation of CT scans in these patients.

Bilateral Hilar Foci on 18F-FDG PET Scan in Patients Without Lung Cancer: Variables Associated with Benign and Malignant Etiology

In patients with nonlung cancer, in particular colorectal, foci of symmetric and mild uptake limited to the hilar regions that are stable on 2 sequential PET studies despite intervening anticancer therapy are likely related to a benign etiology.

PURPOSE To develop guidelines for performing and interpreting positron emission tomography (PET) imaging for treatment assessment in patients with lymphoma both in clinical practice and in clinical

In the last decade, PET-only systems have been phased out and replaced with PET-CT systems. This merger of a functional and anatomical imaging modality turned out to be extremely useful in clinical

Current developments show that where image features can be comprehensively described, computer analysis can replace the perception function of the observer, whilst the function of interpretation can in some cases be performed better by artificial neural networks.
