In this study, we aimed to develop a hybrid method for automated detection of high-uptake regions in the breast and axilla using dedicated breast positron-emission tomography (db PET) and whole-body PET/computed tomography (CT) images. In our proposed method, high-uptake regions in the breast and axilla were detected using db PET images and whole-body PET/CT images. In db PET images, high-uptake regions in the breast were detected using adaptive thresholding technique based on the noise characteristics. In whole-body PET/CT images, the region of the breast that includes the axilla was first extracted using CT images. Next,...

Authors: Shah AR, Al-Hanayneh M, Chowdhry M, Bilal M, Singh S Abstract Liver biopsy plays an essential role in the diagnosis, evaluation and management of a vast proportion of liver diseases. Conventionally, percutaneous and trans-jugular approaches have been used to obtain liver biopsies. Endoscopic ultrasound guided liver biopsy (EUS-LB) has emerged as a safe and effective alternate in the past two decades. EUS-LB carries a role in evaluation of both benign and malignant diseases of the liver. It can offer higher resolution imaging of the liver and can detect smaller lesions than computed tomography scan of the a...

Authors: De Vito C, Papathomas G T, Pedica F, Kane P, Amir A, Heaton N, Quaglia A Abstract Systemic symptoms such as fever and fatigue are non-specific manifestations spanning from inflammation to neoplasia. Here we report the case of a 34 year-old man who presented with systemic symptoms for four months. CT-scan and MRI revealed a 3.4 cm arterialized hepatic lesion and a 7 cm paraduodenal mass. Surgical resection of both lesions and histological examination revealed an inflammatory hepatocellular adenoma and a unicentric plasma cell type of Castleman disease. Moreover, a diffuse AA amyloid deposition in the liver ...

CONCLUSIONS: The histological presence of necrosis and of fibrosclerosis after CIRT at the histological analysis supports the previous clinical evidence on the efficacy of CIRT. Volumetric stability of the residual mass should be considered as a success of treatment. In cases of a volumetric increase of the mass, a CT needle biopsy should always be performed. In our series, during the follow-up, the FDG-PET was able to promptly detect an increased uptake in the case which later was histologically defined as dedifferentiated chordoma.

AbstractPurposeCardiac amyloidosis (CA) is a rare cause of heart failure with frequently delayed diagnosis, because specific early signs or symptoms are missing. Recently, direct amyloid imaging using positron emission tomography/computed tomography (PET/CT) has emerged.The aim of this study was to examine the performance of18F-florbetaben-PET/CT in detection of CA, and compare it to echocardiography (echo), cardiac MRI (CMR) and scintigraphy. Additionally, the use of18F-florbetaben-PET/CT for quantification of amyloid burden and monitoring of treatment response was assessed.MethodsTwenty-two patients with proven (n&thinsp...

AbstractPurposeUsing current optical imaging techniques and gamma imaging modalities, perioperative sentinel lymph node (SLN) identification in colon cancer can be difficult when the SLN is located near the primary tumour or beneath a thick layer of (fat) tissue. Sentinel lymph node mapping using PET/CT lymphoscintigraphy combined with real-time visualization of the SLN using near-infrared imaging has shown promising results in several types of cancer and may facilitate the successful identification of the number and location of the SLN in early colon cancer.MethodsClinical feasibility of PET/CT lymphoscintigraphy using pr...

Conclusion: In view of the poor specificity, the current study calls for reconsideration of the universal recommendation of dedicated brain imaging (in addition to PET/CT scan) among NSCLC patients beyond stage I. PMID: 31116030 [PubMed - as supplied by publisher]
