Aims and objectives: Contrary to the commonly used classification for diffuse idiopathic skeletal hyperostosis (DISH) by Resnick, degenerative intervertebral disease (DID) were previously described in DISH. We aimed to assess for the presence and prevalence of such changes on CT examinations of the thoracic spine of sub[...]

Methods and materials: Intervertebral space (D1-L1) on chest CT examinations of DISH subjects were retrospectively evaluated for the presence of DID. Parameters evaluated included disc space height (D7-D11), disc protrusion, subchondral cysts/sclerosis, Schmorl nodes, vacuum phenomenon, and degenerative changes in the po[...]

Results: A total of 158 subjects (DISH/Control 1/Control 2: 54/54/50, M/F: 106/52, average age: 70.6 years) were evaluated. Average osteophyte score was significantly higher in DISH compared to controls (DISH/Control 1/Control 2: 5.22/1.72/2.68/, p<0.001). Average intervertebral disc height was significan[...]

Conclusion: In conclusion, we have shown that intervertebral disc height is reduced in DISH subjects, costochondral degenerative changes are more prevalent and except for vacuum phenomenon, other intervertebral degenerative changes are as common in DISH as in control subjects. These findings serve to reiterate [...]

Learning objectives: To describe the normal post-operative imaging appearance of anterior cruciate ligament (ACL) reconstruction on magnetic resonance imaging (MRI). To review the causes and imaging appearances of the various complications of ACL reconstruction.  

Background: The ACL is the most commonly injured and reconstructed ligament in the knee. MRI is the gold standard for imaging ACL reconstruction. Indications for post-operative ACL imaging include persistent instability, postoperative stiffness, postoperative re-injury, and evaluation prior to graft revision. G[...]

Findings and procedure details: The anterior cruciate ligament is an important stabilizer of the knee joint and is crucial in preventing anterior translation of the tibia in relation to the femur. Rupture of the ACL is among the most commonly seen sports injuries, with about 250,000 new ruptures a year estimated in the United Stat[...]

Conclusion: Given the increasing number of patients who undergo ACL reconstruction, familiarity with the normal post-operative imaging appearance and the imaging appearance of complications of graft reconstruction is critical in guiding treatment management.

N. M. Salamon, C. Van Langenhove, K. L. Verstraete; Ghent/BE

Direct link to access the poster (click here)

Aims and objectives: The aim of this study was to determine the correlation between anthropometric (age, body mass index, body weight and length) and morphometric parameters (lumbar disc height, vertebral body height and subcutaneous fat thickness) on MRI of the lumbar spine (Fig. 1). To our knowledge, no study has ever[...]

Methods and materials: A retrospective study was performed in 50 patients, aged 19 to 72 years old (mean: 46,3 y; median 45,5 y), who underwent an MRI of the lumbar spine. Body weight and length were measured in all subjects. MRI was performed on two 1,5 T MR units with a specific lumbar spine protocol. For this study onl[...]

Results: I. Disc height (Table 1) Disc height was positively correlated with: + Body length: at all levels + Body weight: at all levels   Disc height was negatively correlated with: -  Age: at levels L3-L4 and L4-L5   II. Vertebral body height (Table 2)   Vertebral body height was posit[...]

Conclusion: 1. Disc height was positively correlated with body length and weight at all levels. It’s logical that when someone is larger, vertebral body height and disc height will also be higher, since body length and weight are constitutional determinants of the human body. The positive correlation of weight [...]

Learning objectives: To clarify the radiological approach to conditions that show abnormal subcutaneous fat distribution.

Background: Adipose tissue is known to play multiple and complex roles for mechanical cushioning and as a secretory organ that regulates energy balance, homeostasis, appetite, inflammation, insulin sensitivity, and lipid metabolism (1). Radiologists encounter abnormal fat distribution in various congenital or a[...]

Findings and procedure details: (A) Generalized 1) Congenital generalized lipodystrophy (CGL)  Congenital (genetic) lipodystrophy has been reported in about 1000 patients with various types related to the pattern of fat loss and genetic molecular defect (2,3). Congenital generalized lipodystrophy is an autosomal recess[...]

Conclusion: Radiologists should understand the typical imaging finding and disease spectrum of abnormal deposition of subcutaneous fat. Although the underlying conditions are diverse, radiological findings can be the key for early assessment suggesting the proper methods for definitive diagnosis.

Direct link to access the poster (click here)

Aims and objectives: Foam rolling has been developed to a popular intervention and has been established in training and rehabilitation. Despite the growing application of foam rolling, there is a lack of studies that observed its effects on cellular and physiological level. Thus the aim of the present study was to asses[...]

Methods and materials: In total, 21 healthy participants (age 25 ± ( years, height 177 ± 9 cm, body weight 74 ± 9 kg) were recruited from the medical and sports faculty. Arterial tissue perfusion was determined by terms of spectral Doppler and power Doppler ultrasound, represented as Peak Flow (Vmax), Time Average Velocit[...]

Results: Our results indicate that arterial blood flow of the lateral thigh increases significant following foam rolling exercises in comparison to baseline conditions (p<0.05). We could detect a relative raise for Vmax of 73.6% (2 min) and 52.7 % (30 min) (p<0.001), for TAMx of 53.2% (p<0.001) and [...]

Conclusion: An increase of arterial blood flow suggests a role for the acute phase after foam rolling. Our data may contribute to the understanding of local physiological reactions of selfmyofascial release. The advantages of enhanced blood flow might be important for warmup and recovery and our data support th[...]

Direct link to access the poster (click here)

Aims and objectives: Radiographic atlases have been developed to be used as a standardised guide in the evaluation of individual features of OA. They have both clinical and research value, particularly in the confirmation and grading of OA in patients. The first pictorial atlas to grade ankle osteoarthritis from ankle r[...]

Methods and materials: Ankle radiographs with 2 orthogonal views were obtained from attendances in various clinical settings (outpatient, inpatient, emergency). Images were selected and given a score from the modified Kellgren-Lawrence grading after consensus assessment of the tibiotalar joint by 2 radiology residents ([...]

Results: Objective 1: For the 16-point Kraus score, the inter-rater reliability values calculated using the weighted kappa were higher when compared to the data published by Kraus et al (Tables 3 and 4). There was “substantial” agreement (kw0.63– 0.9) in 15 of 16 Kraus grading categories. Of these, the con[...]

Conclusion: The Kraus atlas is straightforward and reliable despite minimal radiology experience. The 1-point modified Kellgren-Lawrence score alone is sufficient to estimate the severity of ankle osteoarthritis.
