Simultaneous positron emission tomography and magnetic resonance imaging for the detection and characterisation of liver lesions in patients with colorectal cancer: A pictorial review

SummaryPatients with colorectal cancer undergo frequent diagnostic imaging to stage the extent of metastatic disease and assess response to treatment. Imaging is typically via diagnostic contrast ‐enhanced CT or combined FDG‐PET/CT. However, recent research has demonstrated promising benefits of combined FDG‐PET/MRI in oncologic imaging due to the superior soft‐tissue contrast of MRI. The extent of both intrahepatic and extrahepatic disease is important in establishing treatment opti ons for colorectal cancer patients, and FDG‐PET/CT and dedicated liver imaging are often both required. FDG‐PET/MRI offers the advantage of a single examination which can be completed within a similar duration as dedicated liver MRI imaging. This improves patient convenience and anatomical co‐ registration between PET and MRI imaging and provides a potential cost benefit. The diagnostic benefits of FDG‐PET/MRI include the simultaneous characterisation of focal liver lesions, exclusion of extrahepatic disease, the detection of additional hepatic metastases and extrahepatic disease, and t he multi‐parametric assessment of treatment response. This pictorial review highlights examples of these benefits.

CONCLUSION: Parasitic diseases, such as those caused by Fasciola hepatica, should be kept in mind in the differential diagnosis of primary or metastatic liver tumors, such as colorectal cancer liver metastasis, in patients living in endemic areas. PMID: 31528248 [PubMed]

By now most of us are familiar with Brexit, the UK’s pending divorce with the European Union. But in a play on that term, British doctors are also moving towards an exit they’ve dubbed “TRexit” from the most common sort of prostate biopsy: the transrectal ultrasound guided biopsy, or TRUS. Men who test positive on the PSA cancer screening test will usually have a prostate biopsy that’s performed in either of two ways. With a TRUS, doctors guided by an ultrasound machine can sample the prostate using a biopsy needle inserted through the rectum. Alternatively, the biopsy needle can be inserted (...

Conclusion: This experiment yielded a workable geometry for foil irradiation given the activity produced. Despite low synthesis yields, several steps were identified for improvement. Further investigation found that additional steps should be taken when chelated compounds are present using the OnGuard II M cartridge; forgoing these steps results in a smearing of yellow iron in the cartridge, which was observed. The counts of free vanadium indicate the filtration was not completely successful; the additional procedure could produce higher yields. PET/MR imaging validated the increased uptake of this novel radiotracer for po...

Chapple, Francesco Montorsi, Nicolas Mottet, Monique J. Roobol, Jens Sønksen, Manfred Wirth, Hendrik van PoppelAbstractProstate cancer (PCa) is one of the first three causes of cancer mortality in Europe. Screening in asymptomatic men (aged 55–69 yr) using prostate-specific antigen (PSA) is associated with a migration toward lower staged disease and a reduction in cancer-specific mortality. By 20 yr after testing, ...

Conclusions The recent, first randomized clinical trial demonstrated overall and progression free survival benefits after SBRT to oligometastatic disease which supports prior retrospective case series (6). The spine is a common site of metastatic bone disease, and as high quality data continue to mature, along with completion of additional randomized clinical trials, it is expected that utility of SBRT to the spine will increase in the future. Spine SBRT is unique due to the requirement of sharp dose falloff to prevent serious neurologic morbidity. With recent advances in radiotherapy planning, robotic patient positionin...

Conclusions Several model systems are now available to characterize the MSC-tumour interplay in the TME. These offer early promise in establishing robust preclinical platforms for the identification of crucial molecular pathways and for the assessment of clinical efficacy of novel drugs to inhibit cancer development and progression. However, selection of the right model for a given study should be shaped on the purpose, and should also consider fixed biological, biochemical, and biophysical parameters according to the specific tumour type. Finally, in order to get reliable and useful results to be translated to the clinic...

This study protocol was approved by the Institutional Review Board of the hospital. Data Collection Demographic and clinical data were retrieved from medical records in the hospital’s centralized database. These data included the age at diagnosis, International Federation of Obstetrics and Gynecologic (FIGO) stage, tumor histology and grade, type of surgery, and types and cycles of chemotherapy. Disease staging was based on the 2014 FIGO staging system. Optimal debulking surgery was defined as residual tumors with maximal diameters less than 1 cm; the others were defined as suboptimal debulking surgery. Disease rec...
