Sentences with phrase «cerebellar ccf»

A correlation of Rostral Cerebellar CCF Percentage and Cerebellar Brain Percentage revealed a positive relationship in the CKCS group (r = 0.4886 [p = 0.0008]-RRB-, but not in the small breed dog (r = 0.2363 [p = 0.1532]-RRB- or Labrador (r = 0.2562 [p = 0.2065]-RRB- groups.

Cerebellar crowding in the rostral and caudal parts of the CCF was expressed as the percentage of that part of the CCF which was occupied by cerebellum (Caudal Cerebellar CCF Percentage and Rostral Cerebellar CCF Percentage).

The volume of the cerebellum is expressed as a percentage of the caudal cranial fossa volume (Panels A and B: Cerebellar CCF Percentage) and a percentage of the total brain volume (Panels C and D: Cerebellar Brain Percentage).

Pearson r correlation between Age vs. Cerebellar CCF Percentage (r = − 0.2889, p = 0.1084) and Age.

The CM / SM group had a significantly larger Cerebellar CCF Percentage (54.0 ± 0.7 % vs. 50.5 ± 0.75 % [p = 0.0034]-RRB- and a significantly larger Cerebellar Brain Percentage (9.56 ± 0.2 % vs. 8.75 ± 0.2 % [p = 0.0232]-RRB- than the CM group (Figure 3).

Crowding of cerebellum is defined as the percentage of the volume of each part of the caudal cranial fossa (CCF) which is occupied by cerebellar parenchyma (panel A: Rostral Cerebellar CCF Percentage, panel B: Caudal Cerebellar CCF Percentage).

The relationship between cerebellar overcrowding and relative cerebellar volume was tested with a Pearson r correlation of Caudal Cerebellar CCF Percentage and Cerebellar Brain Percentage: The CKCS group demonstrated a positive correlation (r = 0.5204 [p = 0.0003]-RRB-, whilst the SB (r = 0.1277 [p = 0.4449]-RRB- and LD (r = 0.3016 [p = 0.1342]-RRB- group did not.

CKCS had a larger Cerebellar CCF Percentage (CKCS 51.9 ± 0.3 % vs. SB 48.1 ± 0.7 % [p < 0.0001] and LD 41.6 ± 0.8 % [p < 0.0001]-RRB- and Cerebellar Brain Percentage (CKCS 9.00 ± 0.1 % vs. SB 7.63 ± 0.2 % [p < 0.0001] and LD 7.60 ± 0.2 % [p < 0.0001]-RRB- compared to the other groups (Figure 3).

Crowding of cerebellum is defined as the percentage of the volume of each part of the caudal cranial fossa (CCF) which is occupied by cerebellar parenchyma (Rostral Cerebellar CCF Percentage and Caudal Cerebellar CCF Percentage).

Not exact matches

We also found in CKCS that cerebellar crowding in the caudal CCF is more sensitive to changes in relative cerebellar volume than cerebellar crowding in the rostral CCF, which is consistent with the theory that increased cerebellar volume results in the cerebellum shifting caudally and causes obliteration of dead space in the caudal CCF.

Our results support hypothesis iii) which states that in CKCS an increase in relative cerebellar volume is correlated with an increase in cerebellar crowding in the caudal CCF.

In order to assess the clinical significance of cerebellar volume and CCF volume as prognostic indicators, further cohort and longitudinal studies are needed.

Previous volumetric studies in CKCS have shown that there is an association between SM and CCF parenchyma volume [19], [26], but this is the first time that Cerebellar volume has been linked to SM.

These parameters are accepted standards in canine brain volume measurement as they have been used in a study of cerebellar atrophy [22] and CCF parenchyma volume [18], [19].

We found that increased cerebellar volume in the CKCS is correlated with crowding of the cerebellum in the caudal CCF and this is not seen in Labradors or small breed dogs.

In contrast to small breed dogs and Labradors, CKCS exhibit correlation between increased cerebellar volume and cerebellar crowding within the caudal CCF, suggesting that CCF growth in CKCS is not keeping pace with the growth of the cerebellum.

Furthermore, the degree of cerebellar crowding in the caudal CCF is correlated with increased volume of the cerebellum in CKCS and this is not seen in small breed dogs or Labradors.

Cavalier King Charles Spaniels (CKCS) showed a relationship between cerebellar crowding and volume in both the rostral CCF (p = 0.0008) and caudal CCF (p = 0.0003) and Labradors (LD) and small breed dogs (SB) did not.

Our results show that the CKCS has a relatively larger cerebellum than small breed dogs and Labradors and provide evidence that increased cerebellar volume in CKCS is associated with crowding of cerebellum in the caudal part of the CCF.
