MRI machines can cost hospitals several million dollars
The cost of MRI machines can vary depending on various factors, with prices ranging from $150,000 to several million dollars. The strength of an MRI machine's magnetic field is a crucial factor influencing its cost, with machines in the 3.0T range typically costing 25% more than those in the 1.5T range. The image quality and level of detail achieved are directly proportional to the strength of the magnetic field. While low-field MRI machines can be purchased for as little as $150,000, state-of-the-art, high-powered machines can cost up to $3 million.
The size of the patient bore, which refers to the width of the tube in which the patient lies during the scan, is another factor that impacts the cost. Wider bore systems, typically measuring 70 cm, offer greater patient comfort and tend to be more expensive, sometimes costing 50% more than the standard 60 cm bore systems.
Additionally, the purchase price of an MRI machine is not the only expense to consider. Installation costs can be significant, especially since MRI machines require specialised facilities, such as magnetically sterile clean rooms, to ensure proper functioning and safety. These installation costs can add up to hundreds of thousands of dollars, bringing the total cost of acquiring and installing an MRI machine to several million dollars.
Furthermore, the ongoing maintenance and operational costs of MRI machines can be substantial. The powerful magnetic fields and advanced cooling systems required for MRI machines result in high electricity consumption, with the average MRI scan using 15 kWh of electricity, significantly more than the average U.S. home. Additionally, the use of contrast dyes containing gadolinium, which enhances scan detail, can add hundreds of dollars to the cost of each scan.
The skilled personnel required to operate and interpret MRI scans also contribute to the overall expense. Radiologists and radiology technologists need specialised training in areas such as electromagnetic fields, cryogenics, high-powered computing, and human anatomy. These factors highlight why MRI machines and the associated scans can carry a hefty price tag for hospitals and healthcare facilities.

MRI scans can be uncomfortable for patients due to enclosed spaces
MRI scans are a crucial diagnostic tool that uses a large magnet, radio waves, and a computer to create detailed images of the inside of the body. While the procedure is typically painless, it can be uncomfortable for patients due to the enclosed space of the scanning machine.
There are two main types of MRI machines: closed bore and open. Closed bore machines have a narrow, tube-like structure with a diameter of 60 cm, providing the highest magnetic strength and clearest images. However, the enclosed nature of these machines can trigger feelings of claustrophobia and anxiety in some patients. The shape and dimensions of the closed bore MRI can be tightly confined, causing discomfort and distress during the scan. For individuals with claustrophobia, obesity, or those who cannot lie flat for extended periods, closed bore MRI scans may not be a suitable option.
On the other hand, open MRI machines provide a more comfortable experience as they are open on all four sides, eliminating the enclosed space. This design allows for easier scanning of children and individuals with physical disabilities. Additionally, open MRI systems have weight-bearing features, enabling patients to be scanned in a standing position, which can be beneficial for certain diagnoses. While open MRI machines offer improved comfort, they produce lower-quality images due to reduced magnetic strength.
To alleviate discomfort during MRI scans, patients with claustrophobia or anxiety can discuss options for sedation or anesthesia with their healthcare provider. It is important to note that the loud noises associated with MRI scans can also contribute to patient discomfort, and earplugs or headphones are typically provided to protect hearing and reduce noise disturbance.
While MRI scans can be uncomfortable due to the enclosed space, advancements in technology have led to ongoing improvements in patient comfort, such as increased "T" strength in open MRI systems and patient-comfort adaptations in closed bore machines.

MRI machines vary in quality, with higher-quality machines producing better images
The number of MRI machines in a hospital varies depending on the size and location of the hospital, the availability of funding, and the demand for MRI services in the surrounding area. On average, there are 10.8 MRI units per million people in Canada, with a higher density of units per million people in Yukon, Quebec, and New Brunswick.
MRI machines vary in quality, and higher-quality machines produce better images. The quality of MRI images is influenced by several factors, including the strength of the magnetic field and the technology used. MRI machines with stronger magnetic fields, typically 1.0 tesla (T) or greater, produce higher-resolution images with improved clarity and detail. These high-field magnets are commonly found in closed MRI systems, which are known for their superior image quality.
Closed-bore MRI machines utilize a ring of magnets that form an open hole or tube where the patient lies during the scan. While these closed systems can cause anxiety and discomfort due to their enclosed design, they consistently deliver the highest quality images. The strong magnetic fields enable better differentiation between fat and water molecules, resulting in enhanced resolution, particularly for smaller body parts.
In contrast, open MRI systems employ magnets with field strengths typically below 0.5T, resulting in lower-resolution images. The open design of these machines provides more space and comfort for patients, especially those with claustrophobia or larger body types. However, the lower magnetic field strength can make it challenging to distinguish between fat and water during the scan, leading to reduced image quality.
