EE-094 - CT update on Gastric cancer - diagnosis to template reporting: Radiologist’s perspective on Surgeon's requisite
Abstract
Objectives
►Patient preparation to CT image acquisition in suspected gastric cancer
►Normal CT anatomy and embryology of stomach
►CT Staging and lymph nodal spread of gastric cancer
►Design an efficient reporting template
►Knowledge of surgical techniques in stomach cancer for the radiologists
Background
Gastric cancer is the fifth most common neoplasm, and third most common cause of cancer related mortality in the world. Approximately 40% patients present with metastasis at the time of diagnosis. Major bulk of gastric malignancies is formed by adenocarcinoma.
The purpose of MDCT is detection and localization of disease with metastatic work up and staging.
An algorithm based reporting that caters to clinical and surgical queries contributes significantly to treatment planning, consequently to patient outcome.
Imaging findings OR Procedure findings
►Imaging findings are assessed based on site of lesion and appearances, such as polypoidal, ulcero-proliferative or circumferential involvement. Contrast enhancement and transmural infiltration are analyzed.
►Assessment of pericardial, lesser/greater curvature, supra/infrapyloric nodes, and nodes along vessels and ligaments is done.
►Solid organ, peritoneal, extra peritoneal and bone metastasis are assessed.
► Evaluation of entire bowel to look for synchronous lesions is done.
►Based on above described findings, final staging is done.
Conclusion
►MDCT is indispensable in stomach cancer imaging.
►Accurate staging is also possible with MDCT.
►Standardized reporting format helps in familiarizing radiologists with “what to report” and helps in better surgical planning.
►Knowledge of surgical techniques helps in post operative reporting and better communication with the surgeon.
EE-182 - Volume perfusion CT (VPCT) pancreas: Breaking the ice!! from basics to advanced – Pancreatitis and Beyond!
Abstract
Objectives
Why and when to do VPCT of the pancreas
VPCT pancreas scanning technique
Comparison of CT and MR perfusion
Various types of mathematical models for postprocessing of VPCT
Glossary of terms with definitions used in CT perfusion
List various vendor-wise specific CT perfusion parameters
Comparison of Dual energy CT with CT Perfusion for pancreatic pathologies- latest trend
Ultra-low-dose pancreatic perfusion CT
Background
Volume perfusion CT (VPCT) is a relatively new modality that has been increasingly used for various pathologies over the last years. VPCT enables the measurement of functional parameters of tissue vascularity like blood flow (BF), blood volume (BV) and the permeability of capillaries (permeability surface area product, or k-trans).
Imaging findings OR Procedure findings
Normal pancreas has perfusion value of 1.25-1.66 mL/min/mL.
There is an age-dependent physiological decline in pancreatic perfusion.
Pancreatic perfusion is reduced in patients with diabetes.
Early prediction of pancreatic necrosis - VPCT is found to have a sensitivity and specificity of 100% and 95.3%. Blood flow (BF) and blood volume (BV) parameters show reduction compared to normal pancreas.
Pancreatic tumors such as islet cell tumors show increased perfusion values.
Perfusion CT has been found to be useful predictor of effect of pancreatic tumor treatment with anticancer drugs.
Conclusion
VPCT of pancreas has achieved great strides as functional technique since its inception and its scope in the clinical and research setting is escalating.
In future, dual-energy single scan CT may be more useful in quantification of tissue vascularity as radiation dose is much less in single scan DECT compared to CT perfusion
