DETECTING SYNCHRONOUS PARATHYROID ADENOMA AND FALSE-POSITIVE FINDINGS ON TECHNETIUM-99M MIBI SINGLE PHOTON-EMISSION COMPUTED TOMOGRAPHY/COMPUTED TOMOGRAPHY

Detecting Synchronous Parathyroid Adenoma and False-Positive Findings on Technetium-99m MIBI Single Photon-Emission Computed Tomography/Computed Tomography

Technetium (Tc)-99m-methoxyisobutylisonitrile (MIBI) single photon-emission computed tomography/computed tomography (SPECT/CT) is now being used increasingly for preoperative localization of parathyroid adenomas.Tc-99m-MIBI scintigraphy in a 52-year-old man with a diagnosis of primary hyperparathyroidism revealed two focal areas with retention of r

A Two-Step Estimation Method for a Time-Varying INAR Model

This paper proposes a new time-varying integer-valued autoregressive (TV-INAR) model with a state vector following a logistic regression structure.Since the autoregressive coefficient in the model is time-dependent, the Kalman-smoothed method is applicable.Some statistical properties of the model s1229rs are established.To estimate the parameters o
