Computed Tomography

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Ultrasonography

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...

Imaging Studies I: CT and MRI

Imaging Studies I: CT and MRI

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Issues And Trends In Healthcare Delivery System

Issues And Trends In Healthcare Delivery System

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Imaging Studies for Cardiovascular System III: X-Ray

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Imaging Studies III: Computed Tomography

Imaging Studies III: Computed Tomography

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Summary

Advanced diagnostic imaging use in Medicare patients stabilized after 2005, contrary to policy changes. Physician ordering patterns, influenced by radiology management companies and guidelines, likely explain this trend.

Background:

Advanced diagnostic imaging utilization (MRI, CT, nuclear medicine) in Medicare outpatients increased significantly (72.7%) from 2000 to 2005.
This rise prompted policy concerns regarding healthcare costs and appropriate use.

Purpose of the Study:

To analyze trends in advanced diagnostic imaging utilization among Medicare outpatients after 2005.
To investigate the factors contributing to the observed stabilization in imaging use.

Main Methods:

Analysis of Medicare outpatient claims data to track utilization rates of advanced imaging modalities.
Comparison of utilization trends between physicians' offices and hospital outpatient facilities.
Evaluation of potential policy impacts (e.g., Deficit Reduction Act of 2005) and other influencing factors.

Main Results:

Advanced imaging utilization largely stabilized after 2005.
The stabilization was more pronounced in hospital outpatient facilities compared to physicians' offices.
The Deficit Reduction Act's impact on physician office imaging reimbursement did not fully explain the trend.

Conclusions:

Physician ordering patterns appear to be the primary driver for the stabilization of advanced imaging use.
Radiology business management companies (RBMs) and specialty society imaging guidelines are likely influential factors.
Further research into physician behavior and practice management is warranted.
