A Guide to Buying a CT Scanner for Your Hospital/Clinic or Imaging Center

Introduction

Computed Tomography (CT) scanners are sophisticated imaging device that utilize X-rays and advanced computing technology to generate detailed cross-sectional images of organs and tissues.

In this guide, I’ll explore the diverse types of CT scanners, their applications, and why they are indispensable tools for hospitals and clinics seeking cutting-edge diagnostic capabilities.

Uses of CT Scanners

CT scanners are used to:

·??????? Obtain detailed images of the brain, chest, abdomen, and pelvis.

·??????? Diagnose and monitor conditions such as cancer, cardiovascular diseases, and trauma.

·??????? Guide surgical planning and interventions.

·??????? Screen for certain diseases and abnormalities.

?

Components of a CT Scanner

The main components are:

·??????? A bench the patient can lie down on

·??????? A gantry

·??????? A data acquisition system

·??????? An operating console

Types of Scans CT scanners Can Do

There are different types of CT scanners that use varying technologies and applications to meet specific diagnostic needs and medical requirements.

?

Multislice CT (MSCT)

Multislice CT employs multiple detector rows to capture multiple slices simultaneously, producing detailed cross-sectional images of the body. This technique enables faster scan times, improving efficiency in diagnosing various conditions, including vascular diseases, trauma, and cancer.

?

Electron Beam Tomography (EBT)

Electron Beam Tomography utilizes an electron beam as the radiation source, enabling extremely fast scan times. Primarily used for cardiac imaging, EBT excels in capturing dynamic structures, providing high-resolution images that aid in coronary artery assessments, calcium scoring, and cardiac function evaluation.

?

CT Myelography

CT Myelography combines CT scanning with the injection of contrast material into the spinal canal, enhancing visualization of the spinal cord and nerve roots. This technique is valuable for diagnosing spinal cord abnormalities, disc herniations, and other spinal conditions.

?

CT Angiography (CTA)

CT Angiography involves the injection of contrast material to visualize blood vessels and assess blood flow. This non-invasive technique is widely used to diagnose vascular diseases, such as aneurysms, stenosis, and embolisms, providing detailed 3D images for precise evaluation and treatment planning.

The Cost of a PET Scanner

Several factors determine the cost of this machine. Some of these factors, along with their associated costs, include:

Acquisition: Used lower slice CT machines can cost as low as $35,000, while brand new higher slice CT scanners can cost as much as $2.5 million.

Delivery and installation: Planning the site to ensure it meets federal and state regulations may cost between $20,000 and $40,000 in the US.

Operating costs: On average, it may cost you about $100,000 a year to operate the scanner.

Energy usage: You may pay from $50 to $3,000 per month depending on the model and the patient volume.

Maintenance, repairs, and spare parts: The cost may range from $2000 to $10,000 per month, depending on the machine’s power.

Other factors that could influence how much a CT scanner costs include:

·??????? The brand

·??????? Tube

·??????? Number of slices produced

·??????? Whether it’s a new, used, or refurbished machine

Factors to Consider When Buying a CT Scanner

Before investing in a new or refurbished CT scanner, consider these important factors:

Tech and Specs

The slice count, determined by gantry rotation, sets systems apart. Common configurations include 16-slice for general studies and 64-slice, an industry standard enabling advanced scans like cardiac and perfusion studies.

Premium systems offer 128, 256, 320+ slices, leveraging advanced detectors and software for detailed images in specialized applications.

?

Software Set

Modern CT scanners derive capabilities from both hardware and software. Aligning your clinic's needs with the ideal balance of technical specifications and value is crucial for an informed purchase decision.

?

Tube Type and Usage

The x-ray tube, often referred to as the "glass," serves as the energy source for a CT scanner. Similar to an incandescent light bulb, it has a limited but unpredictable lifespan influenced by usage, make, and model. When considering a refurbished CT scanner, inquire about tube usage, typically measured in mAs or scan seconds.

?

Used, Refurbished, or Brand-New CT Scanner?: Refurbished units offer a lower upfront price, while used scanners may be pricier but potentially in better condition, depending on the supplier. Although a brand-new scanner is the best option, budget constraints may lead to a practical choice of a well-conditioned refurbished or used unit. Remember to check specifications before finalizing your purchase.

?

Support and Service

After purchasing a CT scanner, maintenance becomes vital. New equipment typically comes with a 1-year parts and labor service agreement. Refurbished options may provide a 30-day guarantee with flexible service choices: full parts and labor, parts only, and time and materials. You can include your refurbished system in an existing service contract, whether it's a multi-vendor, OEM service, or Independent Service Provider (ISO) contract.
