The latest version of the artificial intelligence chatbot ChatGPT has passed a radiology board-style examination.
Researchers put ChatGPT to the test using 150 multiple-choice questions modelled on the Canadian Royal College and American Board of Radiology exams.
This breakthrough underscores the vast potential of AI in medical fields, yet it also reveals certain limitations that affect its dependability, two studies said.
ChatGPT, a deep-learning model developed by OpenAI, is known for generating humanlike responses based on the input it receives.
Its pattern recognition abilities allow it to interpret and respond to vast amounts of data, but it sometimes produces factually incorrect responses because of the absence of a source of truth in its training data.
“The use of large language models like ChatGPT is rapidly expanding and will only continue to grow,” said Dr Rajesh Bhayana, an abdominal radiologist and technology lead at University Medical Imaging Toronto, Toronto General Hospital.
“Our research offers valuable insight into how ChatGPT performs in a radiology setting, emphasising its immense potential while shedding light on current reliability issues.”
ChatGPT's usage and influence have been growing significantly. Notably, it was recently named the fastest-growing consumer application in history. It is also being integrated into popular search engines like Google and Bing, which both physicians and patients use for medical inquiries.
The AI chatbot managed to correctly answer 69 per cent of the questions, just short of the passing grade of 70 per cent.
However, it showed a noticeable gap in performance between lower-order thinking (84 per cent) and higher-order thinking questions (60 per cent), particularly struggling with descriptions of imaging findings, calculations and classifications, and the application of concepts.
Given that the AI has not received any radiology-specific training, these struggles were not unexpected.
A newer version — GPT-4 — was released in March, the release was an improved version of the AI including enhanced advanced reasoning capabilities. In a follow-up study, GPT-4 answered 81 per cent of the same questions correctly, exceeding the passing threshold and outperforming its predecessor, GPT-3.5.
Despite these improvements, GPT-4 did not show any progress on lower-order thinking questions and answered 12 questions incorrectly that GPT-3.5 had answered correctly. This inconsistency raises questions about the AI's reliability in information gathering.
“ChatGPT gave accurate and confident answers to some challenging radiology questions, but then made some very illogical and inaccurate assertions,” said Dr Bhayana.
“Given how these models function, the inaccurate responses should not be surprising.”
The studies noted a tendency of ChatGPT to produce inaccurate responses, termed hallucinations. Although less frequent in GPT-4, this tendency still limits the chatbot's current usability in medical education and practice.
Despite the limitations, the researchers see potential in using ChatGPT to spark ideas and aid in the medical writing process and data summarisation, as long as the information is fact-checked.
“To me, this is its biggest limitation. At present, ChatGPT is best used to spark ideas, help start the medical writing process and in data summarisation. If used for quick information recall, it always needs to be fact-checked,” Dr Bhayana said.

The Melbourne Mercer Global Pension Index
The Melbourne Mercer Global Pension Index
Mazen Abukhater, principal and actuary at global consultancy Mercer, Middle East, says the company’s Melbourne Mercer Global Pension Index - which benchmarks 34 pension schemes across the globe to assess their adequacy, sustainability and integrity - included Saudi Arabia for the first time this year to offer a glimpse into the region.
The index highlighted fundamental issues for all 34 countries, such as a rapid ageing population and a low growth / low interest environment putting pressure on expected returns. It also highlighted the increasing popularity around the world of defined contribution schemes.
“Average life expectancy has been increasing by about three years every 10 years. Someone born in 1947 is expected to live until 85 whereas someone born in 2007 is expected to live to 103,” Mr Abukhater told the Mena Pensions Conference.
“Are our systems equipped to handle these kind of life expectancies in the future? If so many people retire at 60, they are going to be in retirement for 43 years – so we need to adapt our retirement age to our changing life expectancy.”
Saudi Arabia came in the middle of Mercer’s ranking with a score of 58.9. The report said the country's index could be raised by improving the minimum level of support for the poorest aged individuals and increasing the labour force participation rate at older ages as life expectancies rise.
Mr Abukhater said the challenges of an ageing population, increased life expectancy and some individuals relying solely on their government for financial support in their retirement years will put the system under strain.
“To relieve that pressure, governments need to consider whether it is time to switch to a defined contribution scheme so that individuals can supplement their own future with the help of government support,” he said.
What the law says
Micro-retirement is not a recognised concept or employment status under Federal Decree Law No. 33 of 2021 on the Regulation of Labour Relations (as amended) (UAE Labour Law). As such, it reflects a voluntary work-life balance practice, rather than a recognised legal employment category, according to Dilini Loku, senior associate for law firm Gateley Middle East.
“Some companies may offer formal sabbatical policies or career break programmes; however, beyond such arrangements, there is no automatic right or statutory entitlement to extended breaks,” she explains.
“Any leave taken beyond statutory entitlements, such as annual leave, is typically regarded as unpaid leave in accordance with Article 33 of the UAE Labour Law. While employees may legally take unpaid leave, such requests are subject to the employer’s discretion and require approval.”
If an employee resigns to pursue micro-retirement, the employment contract is terminated, and the employer is under no legal obligation to rehire the employee in the future unless specific contractual agreements are in place (such as return-to-work arrangements), which are generally uncommon, Ms Loku adds.
Real estate tokenisation project
Dubai launched the pilot phase of its real estate tokenisation project last month.
The initiative focuses on converting real estate assets into digital tokens recorded on blockchain technology and helps in streamlining the process of buying, selling and investing, the Dubai Land Department said.
Dubai’s real estate tokenisation market is projected to reach Dh60 billion ($16.33 billion) by 2033, representing 7 per cent of the emirate’s total property transactions, according to the DLD.

What is blockchain?
Blockchain is a form of distributed ledger technology, a digital system in which data is recorded across multiple places at the same time. Unlike traditional databases, DLTs have no central administrator or centralised data storage. They are transparent because the data is visible and, because they are automatically replicated and impossible to be tampered with, they are secure.
The main difference between blockchain and other forms of DLT is the way data is stored as ‘blocks’ – new transactions are added to the existing ‘chain’ of past transactions, hence the name ‘blockchain’. It is impossible to delete or modify information on the chain due to the replication of blocks across various locations.
Blockchain is mostly associated with cryptocurrency Bitcoin. Due to the inability to tamper with transactions, advocates say this makes the currency more secure and safer than traditional systems. It is maintained by a network of people referred to as ‘miners’, who receive rewards for solving complex mathematical equations that enable transactions to go through.
However, one of the major problems that has come to light has been the presence of illicit material buried in the Bitcoin blockchain, linking it to the dark web.
Other blockchain platforms can offer things like smart contracts, which are automatically implemented when specific conditions from all interested parties are reached, cutting the time involved and the risk of mistakes. Another use could be storing medical records, as patients can be confident their information cannot be changed. The technology can also be used in supply chains, voting and has the potential to used for storing property records.

Dr Amal Khalid Alias revealed a recent case of a woman with daughters, who specifically wanted a boy.
A semen analysis of the father showed abnormal sperm so the couple required IVF.
Out of 21 eggs collected, six were unused leaving 15 suitable for IVF.
A specific procedure was used, called intracytoplasmic sperm injection where a single sperm cell is inserted into the egg.
On day three of the process, 14 embryos were biopsied for gender selection.
The next day, a pre-implantation genetic report revealed four normal male embryos, three female and seven abnormal samples.
Day five of the treatment saw two male embryos transferred to the patient.
The woman recorded a positive pregnancy test two weeks later.
