Neuroendocrine tumors of the stomach, duodenum and pancreas : Value of (hybrid) radiological diagnostics.

[Neuroendocrine tumors of the stomach, duodenum and pancreas : Value of (hybrid) radiological diagnostics]. Radiologe. 2019 Sep 12;: Authors: Rübenthaler J, Auernhammer C, Harun I, Ricke J, Cyran CC Abstract CLINICAL/METHODICAL ISSUE: Neuroendocrine tumors (NET) of the stomach, duodenum and pancreas are rare tumors with a low incidence but the exact tumor localization and staging diagnostics are of critical importance for further planning of treatment. STANDARD RADIOLOGICAL METHODS: Standard primary diagnostic methods include multimodal imaging with computed tomography (CT) and magnetic resonance imaging (MRI) but in 20-50% of the cases the localization of the primary tumor cannot be identified. METHODICAL INNOVATIONS: Modern hybrid imaging procedures combine radiological procedures and functional imaging, e.g. using somatostatin receptor (SSR) positron emission tomography CT (PET)/CT imaging. For the exact diagnostics of the primary tumor and distant metastases morphological and functional aspects can be combined for targeted diagnostics. For primary tumor staging a sensitivity of 80.0% and a specificity of 88.4% are given in the literature. PERFORMANCE: The application of SSR PET/CT led to a change in patient management in 44% of all cases according to a recently published meta-analysis and therefore had a significant influence on the further procedure. ASSESSMENT: The use of SSR PET/CT can provide critical infor...

CONCLUSIONS: This work demonstrate the clinical acceptability of substituting MR converted RSP images instead of CT for IMPT planning of prostate cancer. This further translates into higher contouring accuracy along with lesser imaging dose. PMID: 31734604 [PubMed - as supplied by publisher]

If you want residents to moan, start out the conversation with “when I was a resident….” Well, when I was a resident, computed tomography (CT) scans had just been introduced into the hospital, ultrasound was a rarely used procedure, and magnetic resonance imaging and positron emission tomography were still in the future. We did tomograms, pyelograms, veno grams, and various scans of the spleen, liver, and brain. The imaging options available today are overwhelming. Three-dimensional reproductions of any part of the body; bedside ultrasounds of the brain, heart, abdomen, and pelvis; and scans that show fu...

Authors: Gulak MA, Bornais C, Shin S, Murphy L, Smylie J, Pantarotto JR, Fung-Kee-Fung M, Maziak DE Abstract Background: Patients with lung cancer often experience stressful delays throughout the diagnostic phase of care. To address that situation, our multidisciplinary team created a "Navigation Day," during which patients partake in a single-day visit that comprises nurse-led teaching, social work, smoking cessation counselling, symptom control, and dedicated test slots for integrated positron-emission tomography and computed tomography (pet/ct), pulmonary function tests (pfts), and magnetic resonance i...

ConclusionMesenteric cysts represent a rare cause of intra-abdominal mass. Owing to low prevalence, literature is limited as is guidance on management. Careful pre-operative planning is essential so as to avoid operative complications. Imaging such as USS is of great importance; however Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) may be of more benefit, owing to the complex anatomical relations within which mesenteric cysts can present. Surgical excision is widely reported as the surgical treatment of choice for symptomatic cysts

ConclusionsFixation for cervical instability is a critical component of the management of DS. A minority of patients receiving surgery were identified through asymptomatic screening. There was a high complication risk associated with surgery in our study; however, the addition of rigid fixation has lessened the complication rate compared with previous studies.Level of EvidenceLevel IV.

CONCLUSION: BIA is an accurate method for detecting sarcopenia in adults with cancer prior to treatment and is a viable alternative to CT, dual-energy x-ray absorptiometry, and magnetic resonance imaging in oncology clinical practice. IMPLICATIONS FOR PRACTICE: Bioelectrical impedance analysis (BIA) is an attractive method for identifying sarcopenic patients in clinical practice because it provides an affordable, noninvasive test that can be completed within a few minutes during a clinic visit. BIA does not require highly skilled personnel, and results are immediately available. This systematic review summarizes the l...

Lung cancer has been identified as the leading cause of cancer-related deaths worldwide and one of the most common malignancies in China [1]. More and more non-small cell lung cancer (NSCLC) patients have been observed in the screening projects for detection of early stage lung cancer with the use of low dose computed tomography (CT) [2]. Accurate imaging for evaluation of the Lymph Node Metastases (LNM) could affect the treatment of these patients [3]. Many imaging modalities such as CT, Magnetic Resonance Imaging (MRI), Positron Emission Tomography-CT (PET-CT), as well as other diagnostic techniques like ultrasound-guide...

Abstract Careful study of the clinical outcomes of temporal lobe epilepsy (TLE) surgery has greatly advanced our knowledge of the neuroanatomy of human memory. After early cases resulted in profound amnesia, the critical role of the hippocampus and associated medial temporal lobe (MTL) structures to declarative memory became evident. Surgical approaches quickly changed to become unilateral and later, to be more precise, potentially reducing cognitive morbidity. Neuropsychological studies following unilateral temporal lobe resection (TLR) have challenged early models, which simplified the lateralization of verbal a...
