18F-FDG PET/CT as a semiquantitative imaging marker in HPV-p16-positive oropharyngeal squamous cell cancers.
Nucl Med Commun
PUBLISHED: 10-21-2014
Show Abstract
Hide Abstract
There is evidence that the status of human papilloma virus subtype 16 (HPV-p16) alters the prognosis of patients with oropharyngeal squamous cell cancer (OSCC). We sought to establish whether there is a relationship between HPV-p16 status and F-FDG uptake in the prognosis of OSCC.

Comparison of objective criteria and expert visual interpretation to classify benign and malignant hilar and mediastinal nodes on 18-F FDG PET/CT.

Show Abstract
Hide Abstract
There is widespread adoption of FDG-PET/CT in staging of lung cancer, but no universally accepted criteria for classifying thoracic nodes as malignant. Previous studies show high negative predictive values, but reporting criteria and positive predictive values varies. Using Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) results as gold standard, we evaluated objective FDG-PET/CT criteria for interpreting mediastinal and hilar nodes and compared this to expert visual interpretation (EVI).

Impact of relative head sensitivity differences in multi-head gamma cameras.
Australas Phys Eng Sci Med
PUBLISHED: 04-05-2014
Show Abstract
Hide Abstract
Cerebral perfusion single photon emission computer tomography (SPECT) can be used to identify epileptogenic foci. A (99m)Tc ethyl cysteinate dimer SPECT of the brain showed clinically evident differences in uptake between the CT attenuation corrected image and the Chang attenuation corrected image. The upper right hemisphere of the brain showed apparent diffuse hyperperfusion in the CT attenuation corrected image while the Chang attenuation corrected image, after reconstruction that appears to average projections, showed symmetrical cerebral perfusion. On review of archived patient data, this artefact was also observed in multiple previous cerebral SPECT studies undertaken on the same camera. Phantom investigation was used to identify the cause of the artefact as a difference in relative head sensitivity. The investigation also characterised the extent and nature of this artefact for CT attenuation corrected images, Chang attenuation corrected images and non-attenuation corrected images.

18F-FDG uptake in multiple splenic foci on PET/CT: an unusual case of visceral leishmaniasis.
Clin Nucl Med
PUBLISHED: 02-25-2014
Show Abstract
Hide Abstract
A previously well 48-year-old male patient presented with several months of weight loss, fever, massive hepatosplenomegaly, and pancytopenia. A provisional diagnosis of lymphoma could not be confirmed on blind lymph node or bone marrow biopsies. Referral for 18F-FDG PET was made to identify an appropriate biopsy site. Focal uptake in multiple splenic lesions was seen, with normal FDG uptake elsewhere in the body. Splenectomy was then performed and histology revealed leishmaniasis, with no evidence of lymphoma. Focally FDG avid splenic deposits have never been reported in leishmaniasis and were likely due to nodular red pulp expansion.

Classical skeletal injuries shown on 18F-FDG PET/CT following successful cardiopulmonary resuscitation.
Clin Nucl Med
PUBLISHED: 03-28-2013
Show Abstract
Hide Abstract
Rib and sternal fractures are relatively common following conventional cardiopulmonary resuscitation (CPR). This case demonstrates the 18F-FDG PET/CT appearances of typical CPR-related multiple rib and sternal fractures in a 55-year-old man with suspected cardiac sarcoidosis. The PET/CT scan was performed to assess disease activity of cardiac sarcoidosis, and no active cardiac inflammation was detected. The patient initially presented with an out-of-hospital cardiac arrest and successfully received bystander CPR.

The aim of this study is to assess the comparability and interchangeability of the radionuclide glomerular filtration rate (GFR) using different published techniques, and propose normative data for paediatrics.

Optical differentiation between malignant and benign lymphadenopathy by grey scale texture analysis of endobronchial ultrasound convex probe images.
Chest
PUBLISHED: 09-01-2011
Show Abstract
Hide Abstract
Morphologic and sonographic features of endobronchial ultrasound (EBUS) convex probe images are helpful in predicting metastatic lymph nodes. Grey scale texture analysis is a well-established methodology that has been applied to ultrasound images in other fields of medicine. The aim of this study was to determine if this methodology could differentiate between benign and malignant lymphadenopathy of EBUS images.

Palpation thyroiditis seen on F-18 FDG PET/CT.
Clin Nucl Med
PUBLISHED: 02-03-2011
Show Abstract
Hide Abstract
A 29-year-old woman presented with a new right supraclavicular mass on a background of resection of a malignant melanoma from her right shoulder before 4 years. F-18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) imaging revealed uptake in a right supraclavicular node and the inferior pole of the left lobe of the thyroid gland. Subsequent resection and histology of the right supraclavicular node and the left lobe of the thyroid gland demonstrated metastatic melanoma and palpation thyroiditis, respectively. A number of malignant and benign pathologies of the thyroid demonstrate FDG uptake, with 75% being benign. To our knowledge, the findings of palpation thyroiditis on FDG PET/CT have never been previously described.

Tumor thrombus in the great veins from papillary carcinoma of the thyroid: 131I scan findings.
J. Clin. Endocrinol. Metab.
PUBLISHED: 06-08-2010
Show Abstract
Hide Abstract
Tumor invasion of great veins and forming thrombus is a rare complication in papillary carcinoma of thyroid. Contrast computed tomography, ultrasound, and positron emission tomography scan can demonstrate the thrombus but will not help to diagnose the nature of the thrombus. Demonstration of the cause of the thrombus by (131)I scan is possible because tumor tissue in the vein will be iodine avid, but simple thrombus will not.

The segmental distribution and clinical significance of colorectal fluorodeoxyglucose uptake incidentally detected on PET-CT.

Hide Abstract
Unexpected focal colorectal fluorodeoxyglucose (FDG) uptake is becoming a common clinical dilemma with the increasing utilization of positron emission tomography (PET). These findings may subsequently reveal malignant or premalignant pathology.

FDG PET/CT appearance of benign pilomatricoma.
Clin Nucl Med
Show Abstract
Hide Abstract
A 56-year-old patient was referred for FDG PET/CT with a right preauricular lymph node fine-needle biopsy, suggesting poorly differentiated carcinoma and no obvious primary lesion. There was intense FDG uptake in the right preauricular nodule. The node was excised, and formal histology demonstrated a benign pilomatricoma rather than malignancy. Pilomatricoma is uncommon in adults and an unusual cause for marked FDG uptake, likely due to foreign body inflammation. Pilomatricoma can be either benign or malignant. The marked FDG uptake demonstrated in our patient with benign pilomatricoma also suggests that FDG PET cannot reliably grade this rare condition.

Potential for truncating the scan length of restaging FDG-PET/CT after chemoradiotherapy in head and neck squamous cell carcinoma.
Nucl Med Commun
Show Abstract
Hide Abstract
Fluorine-18 fluorodeoxyglucose PET/computed tomography (CT) is now routinely used for staging and monitoring treatment response in head and neck squamous cell carcinoma (HNSCC). Although most patients with HSNCC have locoregional disease, distant metastases are relatively uncommon and occur predominantly in the lungs.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
