Fig. 1 —Measures of subspecialization as concentration in one field
in relation to years since completion of training. Graph shows newly graduated
radiologists are more likely to have undertaken fellowship than are
radiologists long in practice but that difference is smaller for any
subspecialization and even smaller for spending large percentage of work time
in main subspecialty field. Dashed line indicates fellowship completed; solid
line, even slight specialization; dotted line, 50% or more of clinical work
time in main subspecialty.

Fig. 2 —Measures of subspecialization as concentration in one field
in relation to practice size. Graph shows large differences in relation to
practice size, subspecialization being increasingly likely with larger
practice size. Solid line indicates even slight specialization; dashed line,
50% or more of clinical work time in main subspecialty.

Fig. 3 —Number of fields in which radiologists concentrate in
relation to definition of concentration. Graph shows that by any definition of
concentration, largest fraction of radiologists concentrate in one or two
fields. If concentration is defined as spending 10% or more of time or 5% or
more of time in field, substantial minority of radiologists concentrate in
more than four fields.

Fig. 4 —Number of fields in which radiologists spend 10% or more of
clinical work time in relation to years since completion of training. Graph
shows little systematic trend according to years of experience, concentration
in one or two fields is most common, and substantial minority (typically
approximately 20%) concentrate in more than four fields. Solid line indicates
concentration in no fields; dashed line, concentration in one or two fields;
dotted line, concentration in three or four fields; dotted and dashed line,
concentration in more than four fields.

Fig. 5 —Number of fields in which radiologists spend 5% or more of
clinical work time in relation to years since completion of training. Graph
shows little systematic trend in relation to years of experience,
concentration in one or two fields is most common, and substantial minority of
respondents (typically approximately 30–40%) concentrate in five to
seven fields or seven or more fields. Solid line indicates concentration in
one or two fields; dashed line, concentration in three or four fields; dotted
line, concentration in five to fields; dotted and dashed line, concentration
in more than seven fields.

Fig. 6 —Number of fields in which radiologists spend 20% or more of
clinical work time in relation to years since completion of training. Graph
shows little systematic trend in relation to years of experience and
concentration in one or two fields is most common. Solid line indicates
concentration in zero fields; dashed line, concentration in one field; dotted
line, concentration in two fields; dotted and dashed line, concentration in
three or four fields.

Fig. 7 —Number of fields in which radiologists spend 10% or more of
clinical work time in relation to practice size. Graph shows concentration in
one or two fields is increasingly common with larger practice size. Solid line
indicates concentration in zero fields; dashed line, concentration in one or
two fields; dotted line, concentration in three or four fields; dotted and
dashed line, concentration in more than four fields.
