Next Generation Total-Body PET/CT: Challenges and Opportunities

Next Generation Total-Body PET/CT: Challenges and Opportunities

Clinical Trials and Research, Patient Advocacy, , , ,
Long-axial field-of-view (LAFOV) systems have changed the field of molecular imaging. Since their introduction, many PET centres have installed these next-generation digital systems to provide more detailed imaging and acquire PET images in a single bed position. Indeed, vertex to thigh imaging for oncological indications can be obtained in most of the population with the currently available LAFOV systems. Moreover, Total Body (TB) PET, a subtype of LAFOV, enables imaging the entire patient—from vertex through the toes—with one bed-position for most of the population. This review aims to identify possible challenges and opportunities for PET-centres working with TB and LAFOV…

Another Next Generation PET/CT is coming soon. The Omni 128cm Total Body PET – Small Australian trial at Peter Mac

Another Next Generation PET/CT is coming soon. The Omni 128cm Total Body PET – Small Australian trial at Peter Mac

A Global first for NET.  Omni 128cm Total Body PET at the Peter MacCallum Cancer Centre in Melbourne Australia.  According to Professor Michael Hofman, they have been using the camera for a couple weeks and it is exceeding their expectations.  They're running a short trial comparing results against regular PETs.  The great news is that part of the trial will be a prospective sub-trial around dual FDG/ DOTATATE.  In fact I now know that the first patient  in the world to be scanned was a Pancreatic NET and you can watch a great video of this event below. What is…

Imaging to Monitor Treatment Response in Patients With Advanced Neuroendocrine Tumors

Imaging to Monitor Treatment Response in Patients With Advanced Neuroendocrine Tumors

Patient Advocacy, , , ,
Another episode in the expert opinion series.  I thought this might be useful for some of you after an interesting 'google alert' brought up these discussions.  It comprises a roundtable discussion with known NET specialists and some big hitters too.  "Dr Thor" is a favourite of mine. Worth pointing out that Dr Thor is giving is own view on this and that view may not be the same as your own doctor and/or hospital in terms of frequency and type of imaging devices used.  Nonetheless, his opinions are always interesting. Also, worth pointing out this is based on "advanced" NETs,…

A multicentre validation of the NETPET score (Dual [68Ga]DOTATATE and [18F]FDG PET/CT in patients with metastatic GEPNENs

A multicentre validation of the NETPET score (Dual [68Ga]DOTATATE and [18F]FDG PET/CT in patients with metastatic GEPNENs

Clinical Trials and Research, Patient Advocacy, Survivorship, Treatment, , ,
BackgroundIt's normally the case that the higher the grade/Ki67 in Neuroendocrine Neoplasms (NENs), the less likely the tumours will have somatostatin receptors and therefore be able to take advantage of somatostatin receptor PET (SSTR PET) as the gold standard in nuclear imaging.  This is why most grade 3 NENs will receive [18F]FDG PET/CT which finds glycolytic activity in the tumour and predicts an aggressive disease course and normally a higher histological grade. It can also add to prognostic outcomes, which in turn can add to therapy choice decisions. There is an overlap though, particularly with the recognition of well-differentiated Grade 3…
