Prescribing exercises in T2D – what, how much and how often?

26th February 2022, Dr Chee L Khoo

which exercise?

We all know that, in theory, exercises are always good for our patients with type 2 diabetes (T2D) in more ways than one. There are a few problems though, when putting theory into practice. Most of our patients with T2D not only don’t exercise regularly, they actually don’t know what exercise to do, how they should do it for and how often they are supposed to be doing them.…

Pfizer vaccine adverse reaction – is that myocarditis?

28th January, 2022, Spectrum Medical Imaging


Quite a few months ago, we explored the safety of Pfizer’s Comirnaty vaccine especially in young people. In particular, we looked at the increase in the incidence of myocarditis following Pfizer’s Comirnaty vaccines. We publish the list of symptoms that may suggest myocarditis but diagnosis is not always straight forward.

Medicare has now introduced an item number which allows Cardiac MRIs to be bulk billed if you suspect myocarditis.…

Omicron wave – A GP survival guide

January 7th, 2022, Dr Chee L Khoo

the omicron wave

There is a trend across the medical specialties to make their guidelines a live document as emerging data comes thick and fast these days. 12 months is a long time for once a year updates. But when you have guidelines or protocols that are updated on a daily basis, it could mean that either there are really, really lots of data coming through or those guidelines are not based on scientific data.…

The GE Revolution Ascend – Deep Learning in Radiology

25th December, 2021, Spectrum Medical Imaging

Revolution Ascend

As CT procedure volume grows – reaching an all-time high ahead of the COVID-19 pandemic – so too does the need to optimise CT protocols and expand patient positioning options to help expedite exams and accommodate more patients. The actual scan itself only takes a few minutes and the remainder of the time is dedicated to patient prep – including positioning the patient and identifying the correct protocols and settings, plus image reconstruction and report time.…

Spectrum is now at Sydney South West Private Hospital

25th October 2021, Spectrum Medical Imaging

Sydney Southwest Private Hospital

One of the very few beneficial things over the lockdown period is the easier availability of radiological services. Most radiological practices have reported reduction in throughput during the recent outbreaks. As we emerge from the lockdown, referrals for medical imaging are increasing and with the increase, an increasing wait time for services is happening.…

Quadruple therapy for heart failure – why is there treatment inertia?

9th April 2021, Dr Chee L Khoo

Quadruple therapy

We are all aware of the treatment inertia in the management of patients with diabetes. In patients with heart failure, several drug classes have demonstrated significant but independent survival benefit. Quadruple therapy with an angiotensin receptor–neprilsyin inhibitor (ARNI), evidence-based β-blocker, mineralo-corticoid receptor antagonist (MRA) and sodium glucose cotransporter 2 inhibitor (SGLT2i) can cumulatively reduce the risk of death by 73% over 2 years (1).…

Prostate artery embolisation – available now


29th January 2021, Spectrum Interventional Radiology

Benign Prostate Hypertrophy (BPH) is a prevalent condition in males that results in Lower Urinary Tract Symptoms (LUTS). BPH is present in 50% of males at 50yrs of age and increases to 90% of males at 90 years of age. Apart from trans-urethral resection of prostate (TURP) and dutasteride/tamsulosine, there is another longstanding and tested option.…

Covid-19 vaccine roll out – something to get excited about?

14th December 2020, Dr Chee L Khoo

Covid-19 vaccine

We explored the Covid-19 vaccine candidates in the last issue. You would have read that the Pfizer vaccine has been approved and has been rolled out in UK and US. I have yet to come across the full disclosure of the trial anywhere. The Oxford/AstraZeneca trial has been published in full and it is worthwhile dissecting the study and ponder the implications as other vaccines are being rolled out internationally and will hit Australian shores in early 2021.…

Weekly insulin is coming. Is it any good?

13th December 2020, Dr Chee Khoo


First, we have twice daily then once daily GLP1 injections. This was followed by weekly GLP1 injectables. The same is occurring with the insulins. Once daily insulins have been around for a few years and is well established as basal insulins in patients with type 1 and type 2 diabetes. We now have a weekly insulin coming onto the market.…

New RACGP Diabetes Management Guidelines – what’s new?

8th August 2020, Dr Chee L Khoo

Keeping up-to-date?

Two years is an awfully long time in diabetes management updates. Well, that’s exactly how long it has been since the last RACGP diabetes management guidelines was last updated. There have been a deluge of data pouring in to help guide us in our management of patients with type 2 diabetes. The “handbook” is actually looking more like an encyclopaedia now with 198 pages of information.…

Abbreviated breast MRI – how useful is it?

8th July 2020, Spectrum Radiology

Adjunct screening with dynamic contrast-enhanced (DCE)-MRI was first recommended for women at high (>20%) lifetime risk of breast cancer, facilitating earlier cancer detection and reducing interval cancers. Even in women at average risk of breast cancer, there is evidence that they might also benefit from screening MRI.

Apart from the cost of MRI equipment, other costs include the relatively long acquisition, limiting high-volume patient throughput and interpretation times involved in a full diagnostic protocol.…

Covid-19 – can’t swab? Can xrays help?

We all know how restricted the criteria for swabbing patients for Covid-19. You may consider perhaps, a chest rays may help. Although there are lots of studies describing the “classic” ground glass appearance on CXR or Chest CT, Unfortunately, in practical terms, they are not useful. It may actually endanger your radiology colleagues and their staff unless we work as a team during this difficult period.…
